Abstract
The present document describes a quadrature circuit for a radio frequency receiver. The quadrature circuit comprises a first sub-circuit configured to generate a first baseband, BB, signal at an intermediate frequency, IF frequency, from a radio frequency, RF, signal using a local oscillator, LO, signal at a first phase. Furthermore, the quadrature circuit comprises a second sub-circuit configured to generate a second BB signal at the IF frequency from the RF signal using the LO signal at a second phase. The first and second sub-circuit each comprise an oscillator which is locked to the IF frequency.
