  • Multi-band frequency multiplier
    Patent number: 8901973
    Abstract: A multi-band frequency multiplier configured to generate frequencies and multiplied frequencies in an integrated system. The multi-band frequency multiplier includes a multi-band multiplier core with a multiplier core differential amplifier configured to receive a multiplier input signal. A switchable load impedance connects to the multiplier core differential amplifier, and includes n multiplier sections. Each multiplier section includes a section impedance and a section switch. The multiplier core differential amplifier generates an output signal having a frequency substantially equal to k times the input frequency in a range of a selected one of n critical frequencies when a selected one of the section switches corresponding to the selected one of the n critical frequencies is triggered.
