2 / 36 page  Philips Semiconductors Product specification SA1921 Satellite and cellular dual-band RF front-end 2 1999 Mar 02 853–2121 20917 DESCRIPTION The SA1921 is an integrated dual-band RF front-end that operates at both cellular (AMPS, DAMPS, and GSM) and satellite (1515–1600 MHz) 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 943 MHz with 18.3 dB of gain and an IIP3 of –5 dBm. The wide-dynamic range mixer has a 11 dB noise figure at 943 MHz with 7.2 dB of gain and an IIP3 of +5 dBm. The high-band contains a receiver front-end, 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 3.9 dB at 1550 MHz with a power gain of 22.2 dB and an IIP3 of –11.5 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 transmission • LO input and output buffers • On chip logic for network selection and power down • Very small outline package APPLICATIONS • 800 to 1000 MHz analog and digital receivers • 1515 to 1600 MHz digital receivers • Portable radios • Digital mobile communications equipment PIN CONFIGURATION GND SR01732 21 22 23 24 25 26 27 28 29 30 31 37 38 39 40 41 42 43 1 2 3 4 5 6 18 19 20 7 8 9 10 11 12 44 45 46 47 48 32 33 34 35 36 15 16 17 13 14 Rx ON LOW BAND LO A LOW BAND LO A HIGH BAND LO B HIGH BAND LO A GND LOW BAND IF B LOW BAND IF A HIGH BAND IF B HIGH BAND IF A SYN ON HI/LO N/C GND STRONG SIGNAL GND HIGH BAND LNA IN LOW BAND LNA IN GND LOW BAND LNA OUT N/C V CC GND Figure 1.
