A configurable radio frequency receiver is provided. The receiver has at least one low noise amplifier; an oscillator arrangement for producing a plurality of signals having a first number or a second number of separate phases; and multiple mixer modules having inputs connected to an output of the low noise amplifier. The receiver has a configurable resistor network. The receiver is configured such that it can operate in a first mode with said plurality of signals having said first number of phases or a second mode with said plurality of signals having said second number of phases. The configurable resistor network enables the receiver to operate in the first mode in a first configuration, and the second mode in a second configuration. The mixer modules are employed during the operation of the first mode and the second mode.
