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 f_T 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.
