Abstract:
A receiver having an intermediate frequency error correction circuit includes a mixer having a source input, a local oscillator input, and an IF output, an adjustable frequency local oscillator having an output coupled to the local oscillator input of the mixer, an IF filter having an input coupled to the IF output of the mixer and an IF filtered output, where the IF filter has an IF filter frequency response, and control circuitry coupled to the local oscillator such that the frequency of the local oscillator can be varied to at least: partially correct an IF frequency error.
