Patent ID: 8073414

Claim:
A Radio Frequency Receiver on a Single Integrated Circuit (â€œRFSICâ€), the RFSIC comprising: a mixer; a phase-locked loop (â€œPLLâ€) in signal communication with the mixer, wherein the PLL is configured to receive a PLL frequency reference input signal (â€œPFRI signalâ€) that has a PLL frequency reference input signal frequency (â€œPFRI frequencyâ€) and, in response, the PLL is configured to lock to the PFRI signal and produce a tuning signal, wherein the tuning signal is a voltage signal; and an auto-tuned RF filter in signal communication with both the mixer and PLL, wherein the auto-tuned RF filter is configured to have a frequency response, wherein the auto-tuned RF filter is configured to receive the tuning signal from the PLL, and, in response, adjust the frequency response of the auto-tuned RF filter to the tuning signal, and wherein the mixer, PLL, and auto-tuned RF filter are integrated onto a single integrated circuit (â€œICâ€).
