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 in-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: An RF receiver comprising: an RF signal processing unit for receiving an RF signal, wherein the RF signal processing unit comprises a dynamically reconfigurable RF filter for filtering the RF signal; an analog-to-digital converter for converting the filtered RF signal to a digital signal; and a digital signal processing unit for processing the digital signal to provide at least one channel; wherein the digital signal processing unit is adapted to adjust a respective transfer function of at least one said channel when the RF filter is reconfigured, to at least partially compensate a change in the transfer function of the RF filter.

Abstract: A single tone RF signal generator and a method of generating a single tone RF signal. The single tone RF signal generator includes an output and a power amplifier that has an input. The power amplifier is operable to receive an RF signal including a first harmonic corresponding to a single tone signal to be produced by the signal generator. The power amplifier is also operable to amplify the RF signal. The power amplifier is further operable to provide the amplified RF signal to the output of the signal generator. The single tone RF signal generator further includes a feedback circuit connected between the output of the signal generator and the input of the power amplifier. The feedback circuit is configured to add one or more predistortion harmonics to the RF signal received by the power amplifier for cancelling harmonics in the amplified RF signal provided by the power amplifier.
