trf1015 rf downconverter slws021d june 1996 revised july 1998 1 post office box 655303 ? dallas, texas 75265 low-noise amplifier (lna), radio frequency (rf) mixer, and voltage-controlled oscillator (vco) improved compression mode conversion from rf to intermediate frequency (if) on a single chip suitable for portable 900-mhz cellular and cordless telephones low-current consumption mode 20-pin plastic shrink small outline (ssop) package application-selectable internal or external oscillator description the texas instruments (ti ? ) trf1015 is a single-chip rf downconverter suitable for 900-mhz receiver applications. it combines a low-noise amplifier (lna), a buffered voltage-controlled oscillator (vco), and an rf mixer into a 20-pin ssop package requiring very few external components. minimal power consumption can be further reduced by placing the required modules into operate mode and the remaining modules into standby mode. three modes of operation are provided for both the lna and the mixer: standby, low current, and improved compression. the improved compression mode is suitable for applications that require full duplex capability. the improved compression mode is suitable for maintaining receiver sensitivity in the presence of large interfering signals and provides a low bit-error rate (ber) in digital modulation systems. the three modes of operation are selectable in accordance with the presence of a high or low signal on pd1 and pd2, as shown in table 1. table 1. mode control mode pd1 pd2 standby l l low current h h improved compression l h the lna has a gain of 13 db and a noise figure of 2.2 db. lna input and output characteristic impedances are 50 w . the single balanced rf mixer has a gain of 9 db with a single-sideband (ssb) noise figure of 10 db. the vco has a typical tuning range of 25 mhz using an external varactor and resonator. the vco gain and tuning range can be adjusted to meet the phase-locked loop (pll) design requirement, with an external shunt and feedback capacitors in series with the resonator. a buffered output of the vco provides phase locking capability and can be configured for single-ended or differential operation. the trf1015 is offered in the 20-pin ssop (db) package and is characterized for operation from 40 c to 85 c free-air temperature. these devices have limited built-in esd protection. the leads should be shorted together or the device placed in conductive foa m during storage or handling to prevent electrostatic damage to the mos gates. please be aware that an important notice concerning availability, standard warranty, and use in critical applications of texas instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. production data information is current as of publication date. products conform to specifications per the terms of texas instruments standard warranty. production processing does not necessarily include testing of all parameters. copyright ? 1998, texas instruments incorporated 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 pd1 pd2 aux_lo aux_lo+ osc2 vco_gnd osc1 vco_v cc vco_byp lna_gnd mix_out mix_out+ mix_in mix_gnd lna_gnd lna_in lna_v cc lna_out lna_gnd lna_gnd db package (top view) ti is a trademark of texas instruments incorporated.
