  • Multiple band local oscillator frequency generation circuit
    Patent number: 6816021
    Abstract: A multi-band local oscillator for generating an output oscillator signal of a desired frequency is implemented with a single voltage controlled oscillator providing an input oscillator signal and a switch divider block. The output signal is passed through a selected one of a set of filters for band switching and through a frequency divider and subsequently mixed with the input oscillator signal of the voltage controlled oscillator.
    Type: Grant
