Abstract:
1. A transceiver, comprising: a receive path configured to receive ingoing radio frequency (RF) signals and coupled to produce ingoing digital signals to a processor; down conversion circuitry disposed within the receive path and configured to receive the ingoing RF signals wherein the down conversion circuitry produces down-converted communication signals based on the received ingoing RF signals based on a frequency adjusted oscillation; a phase-locked loop that produces a local oscillation; wherein the processor is configured to generate a digital oscillation correction signal; analog to digital conversion circuitry configured to convert the digital oscillation correction signal to a continuous waveform oscillation correction signal; a first mixer configured to mix a divided local oscillation that is based upon the local oscillation with the continuous waveform oscillation correction signal; and a second mixer that mixes the local oscillation with an output of the first mixer to produce the frequency adjusted oscillation.
