SA1921 Overview
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 bined 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.
SA1921 Key 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 pression during analog
- LO input and output buffers
- On chip logic for network selection and power down
- Very small outline package
SA1921 Applications
- 800 to 1000 MHz analog and digital receivers
- 1515 to 1600 MHz digital receivers
