Abstract:
A novel frequency locked loop for tuning a bandpass filter to a small offset frequency around an RF center frequency is provided. The difference between the bandpass filter frequency and the RF center frequency is generated, a frequency locked loop is used to tune the frequency difference to a reference offset frequency.
