A low cost, highly integrated 5.8 GHz low-IF transceiver for 1.5 Mbps streaming data applications

摘要

A highly integrated 5.8 GHz, SiGe BiCMOS transceiver IC has been developed for use in digital cordless phones, and streaming audio and video applications. The transceiver IC includes a double downconversion receiver, a direct upconversion transmitter, VCO/PLL/modulator, low-IF filter, RSSI and demodulator. This IC has excellent performance with better than -100 dBm receive sensitivity and 0 dBm transmit power output over 125 MHz in the 5.8 GHz ISM band. This transceiver IC supports TDD, BFSK modulation at 1.536 Mbits/sec.
