Abstract:
In one aspect this invention provides a radio frequency receiver for coupling to an antenna. The receiver includes a downconversion mixer, an amplifier having an input coupled to the antenna and an output coupled to a first input of the mixer for providing a received frequency signal to the mixer and a voltage controlled oscillator having an output coupled to a second input of the mixer for providing a mixing frequency signal to the mixer. In the preferred embodiments the components of the amplifier and the voltage controlled oscillator are arranged to exhibit a substantially identical resonant circuit topology and are implemented in the same integrated circuit. In the preferred embodiments the amplifier and the voltage controlled oscillator each include calibration circuitry coupled to a calibration signal for compensating for integrated circuit component value variations, and where a calibration signal used for the voltage controlled oscillator is used as well for the amplifier.
