Abstract: In accordance with an embodiment, a circuit includes a mixer having a signal input port, a local oscillator input port and an output port, a lowpass filter circuit having an input coupled to the output port of the mixer and a terminal configured to be connected to a shunt capacitor, and a difference circuit having a first input coupled to the output port of the mixer, and a second input coupled to an output of the lowpass filter. The output of the difference circuit substantially rejects a DC signal component at the output port of the mixer.

Abstract: A voltage controlled oscillator arrangement is disclosed. The arrangement includes a voltage controlled oscillator and a quadratic extension component. The voltage controlled oscillator has a tuning port. The tuning port is configured to select an operating frequency according to an applied voltage. The quadratic extension component is configured to generate a quadratic tuning voltage that as the applied voltage to the tuning port. The quadratic tuning voltage is generated according to a linear temperature compensation signal.

Abstract: A device and method for testing a mixer. For testing, signals having essentially the same frequency are applied to local oscillator (LO) and radio frequency (RF) inputs of the mixer. The signals phase-shifted with respect to each other and an output of the mixer is measured to provide a result.
