Abstract: The disclosure relates to a module for a radio receiver. The module comprises an input terminal; an output terminal; a main signal path for communicating in-phase and quadrature signals between the input terminal and the output terminal; and a second signal path. The second signal path is connected in parallel with the main signal path and is configured to: extract phase and quadrature signals from the main signal path; filter the extracted in-phase and quadrature signals; detect an error in the filtered, extracted in-phase and quadrature signals; and apply a correction to in-phase and quadrature signals on the main signal path based on the error.

Abstract: A digital down converter is disclosed. The digital down converter includes an input for receiving a sampled signal having a frequency band of interest, sampled at a first sampling rate, a commutator structure for distributing a set of real sampled signals for polyphase filtering, a complex band pass polyphase filter associated with the distributed signals, for generating in phase and quadrature filtered components, a baseband notch filter, and a frequency translator for generating in phase and quadrature components of the frequency band of interest at baseband.
