Abstract:
1. An apparatus for coupling to an antenna, comprising: a downconversion mixer; an amplifier having an input configured to be coupled to the antenna and an output configured to be 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 configured to be coupled to a second input of the mixer for providing a mixing frequency signal to the mixer, where 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 with other components of a front end of the apparatus, where the amplifier and the voltage controlled oscillator each comprises calibration and band selection circuitry configured to be coupled to an input signal for compensating for integrated circuit component value variations, and where the input signal used for the voltage controlled oscillator is also used for the amplifier.
