Abstract: A diversity receiver and a terminal are provided. The diversity receiver includes a first main channel and a first diversity channel, the first main channel includes an antenna diplexer and a first main transmission channel, and the first diversity channel includes a tunable bandpass filter and a first diversity receiving channel. The first diversity receiving channel is coupled to a diversity antenna by using the tunable bandpass filter, and the tunable bandpass filter is configured to: adjust a passband bandwidth of the tunable bandpass filter according to a band bandwidth of a first transmit signal generated by the first main transmission channel and a band bandwidth of a first receive signal received from the diversity antenna, and perform bandpass filtering based on the passband bandwidth on the first receive signal.
