GAIN CONTROL IN A SHARED RF FRONT-END PATH FOR DIFFERENT STANDARDS THAT USE THE SAME FREQUENCY BAND

Disclosed is a radio frequency (RF) communication circuit having an input for receiving an RF signal and providing independently gain controlled signal paths from the input. In a first signal path, the signal is amplified by a constant gain. In a second signal path, the signal is amplified by a cons...

Summary:Disclosed is a radio frequency (RF) communication circuit having an input for receiving an RF signal and providing independently gain controlled signal paths from the input. In a first signal path, the signal is amplified by a constant gain. In a second signal path, the signal is amplified by a constant gain and by a variable gain amplifier.
