general description the max2387/max2388/max2389 low-noise amplifier (lna), downconverter mixers designed for w-cdma applications, are ideal for arib (japan) and etsi- umts (europe) based systems. the max2387/ max2388/max2389 feature ultra-low current consump- tion and exceptionally low noise figures in ultra-small packages. the max2387/max2388 include an lna, a downcon- verter mixer, and a local-oscillator (lo) buffer. the max2389 has an lna and mixer, but minimizes current consumption by omitting the lo buffer. for all devices, the lna and downconverter mixers are optimized for the 2110mhz to 2170mhz band. all devices feature a high-gain mode and a low-gain mode of lna operation. the max2387 has a 32db gain step, and the max2388/max2389 have an 18db gain step. all ics include a shutdown mode, powering down the ic dur- ing the front-end receiver? idle periods. the mixer 3rd-order nonlinearity performance is set using an external biasing resistor. for the max2387/ max2388, mixer performance is optimized for a -10dbm typical drive at the lo buffer input port. the max2389 mixer performance is optimized for a -4dbm typical drive at the lo input port. the lo port for all versions is configurable for either single-ended or differential operation. these devices operate from a +2.7v to +3.3v single sup- ply and are available in ultra-small (3mm ? 3mm) 12-pin leadless packages (qfn). ________________________applications japanese 3rd-generation w-cdma cellular phones dual-mode w-cdma/gsm cellular phones features ultra-low current consumption: 10.7ma (max2387), 9.9ma (max2388), and 7.9ma (max2389) +2.7v to +3.3v single-supply operation mixer nf: 7db ssb cascaded noise figure: 2.3db lna low-gain mode: 32db gain step (max2387) or 18db gain step (max2388/max2389) mixer iip3: 6dbm < 1a shutdown current ultra-small (3mm ? 3mm) 12-pin qfn package max2387/max2388/max2389 w-cdma lna/mixer ics ________________________________________________________________ maxim integrated products 1 max2387/max2388 top view 12 bias 11 gnd 10 lna_in 9 v cc 8 if+ 7 if- 45 lo+ 6 lo- 1 lna_out 2 gain 3 mix_in shdn bias max2389 12 bias 11 gnd 10 lna_in 9 v cc 8 if+ 7 if- 45 lo+ 6 lo- 1 lna_out 2 gain 3 mix_in shdn bias pin descriptions/functional diagrams 19-1834; rev 1; 5/01 evaluation kit available ordering information part temp. range pin-package max2387 egc -40 c to +85 c 12 qfn max2388 egc -40 c to +85 c 12 qfn max2389 egc -40 c to +85 c 12 qfn for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com.

max2387/max2388/max2389 detailed description the max2387/max2388/max2389 include an lna and downconverter mixer. these devices feature a shutdown mode to power down the ic during the front- end receiver s idle periods. each ic operates from a +2.7v to +3.3v single supply and is housed in a 12-pin ultra-small qfn (3mm ? 3mm) leadless package. the max2387/max2388/max2389 are fabricated using an advanced high-frequency silicon germanium process. the lna and mixer nf and iip3 have been optimized to provide excellent rf performance in the 2110mhz to 2170mhz band, while drawing minimal current. for the max2387/max2388, the mixer s performance is optimized for a -10dbm typical drive at the lo buffer input port. the max2389 s mixer performance is opti- mized for a -4dbm typical drive at the lo input port. the lo port for all versions can be driven either single- ended or differentially. lna high/low-gain mode these devices offer two modes of operation for the lna: high-gain mode and low-gain mode, selectable with a gain select pin. the max2387 has a gain of 15db in high-gain mode and -16.6db in low-gain mode. the max2388/max2389 have a gain of 15db in high-gain mode and -2.8db in low-gain mode. matching lna in high-gain mode will ensure matching in low-gain mode. downconverter mixer the receive mixer is a wideband, single-balanced design with exceptional noise figure and linearity. the lo input frequency range is 2330mhz to 2360mhz and the rf input frequency range is 2110mhz to 2170mhz. the mixer is internally matched to 50 ? , thus eliminating any external matching components. lo input buffers the max2387/max2388 feature open-collector lo buffers to increase isolation between the lo and the rest of the system. the max2389 offers a lower current consumption for applications that do not require an lo buffer. rf inputs the mix_in input is typically connected to the lna out- put through an off-chip filter providing image rejection and out-of-band interferers filtering. the lna input and output require an external matching network to 50 ? . note that the mixer input is internally matched to 50 ? . see figure 1, typical application circuits for 2.14ghz. lo inputs the lo+ and lo- pins are internally terminated with 100 ? resistors. ac-couple the local-oscillator signal to these pins. if a single-ended lo source is used, con- nect lo+ to ground using an ac-coupling capacitor. w-cdma lna/mixer ics 8 _______________________________________________________________________________________ pin description pin name function 1 lna_out rf output port for lna. requires external matching. 2 gain lna/mixer gain control input 3 mix_in rf input port for mixer. internally matched to 50 ? . 4 shdn shutdown input. drive low to enable shutdown mode. drive high or connect to v cc for normal operation. 5 lo+ noninverting lo input for lo buffer (max2387/max2388) or mixer (max2389). differential input impedance is 200 ? . ac-couple to gnd when the lo is driven single-endedly. 6 lo- inverting lo input for lo buffer (max2387/max2388) or mixer (max2389). differential input impedance is 200 ? . 7 if- inverting mixer s if open-collector output 8 if+ noninverting mixer s if open-collector output 9v cc supply voltage (+2.7v to +3.3v). capacitively bypass to gnd near the ic. 10 lna_in rf input port for lna. requires external matching. 11 gnd ground 12 bias lna/mixer bias pin. for nominal bias, connect 24k ? 1% resistor to gnd.
if output port the mixer output appears on the differential if+ and if- pins. these open-collector outputs require an external inductor to v cc for dc biasing. this port typically requires a matching network for coupling to an external if filter. figures 1 and 2 show examples of differential and single-ended if port connections. applications information layout a properly designed pc board is essential to any rf/microwave circuit. keep rf signal lines as short as possible to minimize losses and radiation. always use controlled impedance lines on all high-frequency inputs and outputs and use low-inductance connections to ground on all gnd pins. at the mixer outputs, keep the differential lines together and of the same length to ensure signal balance. for the best gain and noise performance, use high- quality components for the lna input matching circuit, and solder the slug evenly to the board ground plane. for the power supplies, a star topology works well to isolate between different sections of the device. each v cc node has its own path to a central v cc . place decoupling capacitors that provide low impedance at the rf frequency of interest close to all v cc connec- tions. the central v cc should have a large decoupling capacitor as well.
