INTEGRATED CIRCUITS SA1920 Dual-band RF front-end Product specification Supersedes data of 1998 Apr 07 IC17 Data Handbook 1999 Mar 02 Philips Semiconductors Philips Semiconductors Product specification Dual-band RF front-end SA1920 DESCRIPTION The SA1920 is an integrated dual-band RF front-end that operates at both cellular (AMPS, GSM and TDMA) and PCS/DCS (TDMA and GSM) frequencies, and is designed in a 13 GHz fT BiCMOS process—QUBiC1. The low-band is a combined low-noise amplifier (LNA) and mixer. The LNA has a 1.7 dB noise figure at 881 MHz with 17.5 dB of gain and an IIP3 of –5 dBm. The wide-dynamic range mixer has a 10 dB noise figure at 881 MHz with 9.5 dB of gain and an IIP3 of +5 dBm. The high-band contains a receiver front-end, doubler and a high frequency transmit mixer intended for closed loop transmitters. One advantage of the high-band architecture is an image-rejection mixer with over 30 dB of image rejection; thus, eliminating external filter cost while saving board space. The system noise figure is 4.2 dB at 1960 MHz with a power gain of 23.5 dB and an IIP3 of –12.5 dB. FEATURES • Low current consumption • Outstanding low- and high-band noise figure • Excellent gain stability versus temperature and supply • Image reject high-band mixer with over 30 dB of rejection • Increased low-band LNA gain compression during analog • LO input and output buffers • Frequency doubler • On chip logic for network selection and power down • Very small outline package APPLICATIONS transmission • 800 to 1000 MHz analog and digital receivers • 1800 to 2000 MHz digital receivers • Portable radios • Digital mobile communications equipment PIN CONFIGURATION HIGH BAND LO B HIGH BAND LO A LOW BAND LO A LOW BAND LO A HIGH BAND IF B HIGH BAND IF A LOW BAND IF B LOW BAND IF A SYN ON 14 Rx ON 24 23 22 21 20 19 18 17 16 15 13 12 11 10 9 8 7 6 5 4 3 2 1 N/C GND Tx B Tx A GND V CC GND MIX IN GND Tx IF B Tx IF A N/C V CC Tx ON V CC HIGH BAND IMAGE SET I GND HIGH BAND LO INPUT LOW BAND LO INPUT GND HIGH BAND IMAGE SET Q GND X2 ON N/C 25 26 27 28 29 30 31 32 33 34 35 36 37 N/C 38 STRONG SIGNAL 39 GND 40 CC 41 GND 42 HIGH BAND LNA IN 43 LOW BAND LNA IN 44 GND 45 LOW BAND LNA OUT 46 GND 47 GND 48 N/C V HI/LO GND SR01435 Figure 1.
