US Patent 10516426 Systems and methods for wideband image-rejecting receivers

A wideband receiver includes an active splitter that splits an electronic signal into first and second signals, first and second reconfigurable RF filters, and first and second reconfigurable IF filters. The first reconfigurable RF filter filters the first signal responsive to a first control signal and mixes the first filtered signal and an in-phase LO signal component to output a first IF signal. The second reconfigurable RF filter filters the second signal responsive to a second control signal to generate a second filtered signal and mixes the second filtered signal and a quadrature phase LO signal component to output a second IF signal. The first reconfigurable IF filter filters the first IF signal responsive to a third control signal to generate a first filtered IF signal. The second reconfigurable IF filter filters the second IF signal responsive to a fourth control signal to generate a second filtered IF signal.
