Abstract :
A monolithic integrated front end for 1.9 GHz wireless applications has been designed and tested. On a single chip, a low noise amplifier, mixer and local oscillator for the receive path, and a second VCO, buffer and power amplifier for the transmitter have been integrated. A 50 /spl Omega/ SSB noise figure of 1.7 dB with conversion gain of 16.5 dB is achieved for the receiver. The transmit section provides 300 mW output power with >30% overall efficiency.
