Abstract
A broadband balanced frequency converter (“BBFC”) in signal communication with a frequency source is disclosed. The BBFC may include a mixer and an active balancing element in signal communication with the mixer.
Claims20
A broadband balanced frequency converter (“BBFC”) in signal communication with a frequency source, the BBFC comprising:
- a mixer;
- and
- an active balancing element in signal communication with the mixer, wherein the active balancing element drives the mixer in a balanced mode with the frequency source.
A method for up-converting a low-frequency input signal to a broadband output signal with a broadband balanced frequency converter (“BBFC”), the method comprising:
- creating a balanced frequency reference signal by balancing a frequency reference signal from a frequency source with an active balancing element;
- and
- mixing the balanced frequency reference signal with the low-frequency input signal to produce the broadband output signal.
A method for down-converting a high-frequency input signal to a low-frequency output signal with a broadband balanced frequency converter (“BBFC”), the method comprising:
- creating a balanced frequency reference signal by balancing a frequency reference signal from a frequency source with an active balancing element;
- and
- mixing the balanced frequency reference signal with the high-frequency input signal to produce the low-frequency output signal.
