maxim integrated 28 detailed description the MAX19757 dual-channel downconverter is designed to provide 8.8db gain, 25.3dbm input ip3 and 10.4db nf for a multitude of 1700mhz to 2700mhz basestation receiver applications. with an optimized lo frequency range of 1800mhz to 2600mhz, this mixer supports both high- and low-side lo injection architectures for 1700mhz to 2200mhz and 2000mhz to 2700mhz rf bands, respectively. independent path shutdown allows the user to save dc power during low-peak usage times or in tdd tx mode. the device integrates baluns in the rf and lo ports, an lo buffer, two double-balanced mixers, and a pair of differential if output amplifiers. the MAX19757 requires a typical lo drive of 0dbm and a supply current typically 300ma at band center and 350ma across the rf frequen - cy band to achieve the targeted linearity performance. applications information independent channel shutdown control pins pd1 and pd2 can be used to independently enable/disable the two mixer channels. table 1 sum - marizes the relevant settings for enabling/disabling each channel. both channels can be switched on and off in uni - son by tying pd2 to ground and switching pd1. the pd1 and pd2 inputs have an internal 50k pulldown resistor which can be used to set a logic-low if left unconnected. lo port select as with most of maxims dual rx mixers, the MAX19757 includes an lo select control (losel) for use in systems with multiple lo synthesizers. losel controls the active lo port selection. setting losel high (v cc ) selects lo port 1 while losel low (ground) selects lo port 2. the losel input has an internal 50k pulldown resistor which can be used to set a logic-low if left unconnected. lo buffer standby mode (synthesizer pulling prevention feature) to minimize lo port disturbances in transceiver systems that reuse the lo for transmit, the active front-end circuitry of the MAX19757 lo port can be left on while disabling the selected rx path(s). toggling the stby pin high (v cc ) will place the selected lo port driver in a constant on state, ensuring a buffered termination for the external synthesizer during main and/or diversity path shutdowns. depending on the application, this buffered interface may allow for the elimination of the external buffer that is typically used between the synthesizer and the mixers lo port. the stby input has an internal 50k pulldown resistor which can be used to set a logic-low if left unconnected. lo tune the MAX19757 employs a resonant lo driver scheme for improved efficiency, as well as an internal leveling control loop (alc) to hold the internal lo drive level constant. to extend the frequency range of this topology, two bits of tuning are used to adjust the lo tank resonance. good efficiency is maintained over a typical 150mhz range around the resonant frequency. table 2 settings should be used to select the appropriate lo band for best efficiency and performance. dc currents over lo frequency at the four tune settings can be seen in the typical operating characteristics curves. the minimum bias current cor - responds to the lo tank resonant point. the internal alc loop maintains a constant drive amplitude over the range shown in the curves for different settings. the various specifications and guarantees assume that the appropri - ate lo band is used. the alc loop includes a bias limit circuit to prevent overdrive when operated at an inappro - priate lo frequency. lo_tune1 and lo_tune2 can be driven dynamically by using external control logic or can be set to vcc or ground by using a 0 resistor on the pins. if driven from external logic, v cc must be applied to the device so as to not overcurrent the on-chip esd diodes which could damage the part. the lo_tune1 and lo_ tune2 inputs have an internal 50k pulldown resistor which can be used to set a logic-low if left unconnected. table 1. channel enable/disable states table 2. lo tune states main channel diversity channel pd1 pd2 on on 0 0 off off 1 0 on off 0 1 off on 1 1 desired lo band lo_tune1 lo_tune2 < 2000mhz 0 1 > 2000mhz to < 2200mhz 0 0 > 2200mhz to 2400mhz 1 1 > 2400mhz 1 0 MAX19757 dual, sige, high-linearity, 1700mhz to 2700mhz downconversion mixer with advanced shutdown features www.maximintegrated.com
maxim integrated 29 bias settings since mixer linearity and power are affected by the devices operating points, flexibility was built into the MAX19757 so that the if and lo bias levels can be adjusted using external resistor sets (see the typical application circuit ). customized tradeoffs can thus be made to optimize linearity vs. overall power consumption. the if quiescent bias is set via the current at pin 35 (the r1 value to ground), and the internal lo drive amplitude by the current at pin 29. if amplifer bias adjustments pin 35 of the device, if_radj, must have a resistor to ground for the if amp to function. a nominal if bias of 80ma is obtained with a 4.87k resistor used for r1. a smaller resistance increases the if bias. conversely, a larger resistance decreases the if quiescent bias; the if amp bias current through l1/l2 or l4/l5 of the typical application circuit should not exceed 130ma. lo buffer bias adjustments the internal lo target amplitude can be altered by sinking or sourcing sink current at the lo_vadj pin. to increase the static lo drive, remove r3 from v cc and connect it to ground. the value of r3 should be greater than 10k for this increased drive operation. to reduce overall power consumption by decreasing the lo drive, connect r3 from pin 29 to v cc . the typical application circuit is con - figured for this reduced power consumption mode. static bias operation as outlined above, external resistor sets can be chosen to set the bias schemes for the MAX19757s lo and if amplifier circuits. select r1 and r3 to set the if and lo biases per the guidance provided above. see the typical application circuit for details surrounding the suggested configurations. using the static bias mode will ensure that the mixer deliv - ers a constant level of linearity performance with a con - stant level of power dissipation, regardless of the signal power present on the mixers rf ports. dynamic bias operation the static biasing schemes outlined above provide a con - stant level of linearity for a given current draw. however, in many base station receiver applications, it may not be necessary to maintain exceptionally high levels of linearity performance at all times. iip3 linearity is critical for base station receivers when the radio is operating in the pres - ence of interfering blockers. due to the intermittent nature of these blocking signals, there exists an opportunity to relax the mixers iip3 performance when the blockers are not present. this relaxation of linearity implies that the mixers overall current consumption can be throttled back by a commensurate amount. the MAX19757 capitalizes on this opportunity by employ - ing a novel dynamic biasing scheme which detects the presence of blockers in the if domain, and increases the biases to the if and lo amplifiers automatically. the use of the feature is completely optional (see optional dynamic bias typical application circuit ). in this figure, a few additional components and connections are added or modified to enable this feature. omitting these additional components will force the circuit to revert back to the static biasing scheme. the MAX19757 includes a simple log amp detector that senses the presence of a high-level signal on both of the if paths. if_det_out (pin 11) will yield a signal that swings above or below the internal 1.2v bandgap refer - ence and can therefore be used to source or sink current into the if and/or lo bias adjust pins. as the if signal increases , the if_det_out output decreases down to its 0.4v limit. conversely, as the if signal decreases , the if_det_out output increases to its upper limit of 1.7v. the nominal bias crossing corresponds to an if output level of approximately +10dbm. the if_det cext pin (17) is used to set the attack / decay times of the detector. the effective resistance at this pin is ~ 30k. select a cext value appropriate for the slowest system data rate. typical values for dynamic control of both the if and lo are as follows: r1 = 4.64k, r2 = 5k, r3 = 10k, and cext = 1f . under small-signal conditions, the chip power will decrease ~25% and increase to about +30% with an iip3 increase of ~3dbm. note that the attack/decay times will be affected when the individual paths are subjected to the shutdown states described in table 1 . contact the factory for details. layout considerations a properly designed pcb is an essential part of any rf/ microwave circuit. keep rf signal lines as short as pos - sible to reduce losses, radiation, and inductance. for best performance, route the ground-pin traces directly to the exposed pad underneath the package. this pad must be connected to the ground plane of the board by using multiple vias under the device to provide the best rf and thermal conduction path. solder the exposed pad on the bottom of the device package to a pcb. power-supply bypassing MAX19757 dual, sige, high-linearity, 1700mhz to 2700mhz downconversion mixer with advanced shutdown features www.maximintegrated.com
maxim integrated 30 proper voltage-supply bypassing is essential for high fre - quency circuit stability. bypass each vcc pin with capaci - tors placed as close as possible to the device. place the smallest capacitor closest to the device. see the typical application circuit and table 3 for details. exposed pad rf and thermal considerations the exposed pad (ep) of the devices 36-pin thin qfn package provides a low thermal-resistance path to the die. it is important that the pcb on which the ic is mounted be designed to conduct heat from this contact. in addition, provide the ep with a low-inductance rf ground path for the device. the ep must be soldered to a ground plane on the pcb, either directly or through an array of plated via holes. soldering the pad to ground is also critical for efficient heat transfer. use a solid ground plane wherever possible. table 3. typical application circuit component values designation qty description c1, c6 2 3.0pf 0.1pf 50v c0g cer cap (0402) murata: grm1555c1h3r0b c12, c14 2 5.0pf 0.1pf 50v c0g cer cap (0402) murata: grm1555c1h5r0b c2, c3, c5, c7Cc11, c13, c16Cc20 14 0.01f 10% 25v x7r cer cap (0402) murata: grm155r71e103k c25 1 4.7f 10% 16v x7r cer cap (1206) murata: grm31cr71c475k l1, l2, l4, l5 4 330 nh 5% wire wound ind (0805) coilcraft: 0805cs-331xjlc r1 1 4.87k? 1% resistor (0402) any r3 1 154k? 1% resistor (0402) any t1, t2 2 mini circuits tc4-1w-17 u1 1 maxim MAX19757etx+ MAX19757 dual, sige, high-linearity, 1700mhz to 2700mhz downconversion mixer with advanced shutdown features www.maximintegrated.com
