Abstract
A tunable multi-band receiver supporting operation on a plurality of frequency bands is disclosed. In an exemplary design, the tunable multi-band receiver includes an antenna tuning network, a tunable notch filter, and at least one low noise amplifier (LNA). The antenna tuning network tunes an antenna (e.g., a diversity antenna) to a receive band in a plurality of receive bands. The tunable notch filter is tunable to a transmit band in a plurality of transmit bands and attenuates signal components in the transmit band. One LNA among the at least one LNA amplifies an output signal from the tunable notch filter. The tunable multi-band receiver may further include one or more additional tunable notch filters to further attenuate the signal components in the transmit band.
