Abstract
A frequency mixer that generates out of phase sum signals and uses the out of phase relationship to absorb sum signal energy in an energy absorbing component. A frequency mixer according to the present teachings includes a set of mixing devices that generate a first sum signal and a second sum signal in response to an input signal and a drive signal such that the first sum signal is out of phase in relation to the second sum signal. A frequency mixer according to the present teachings includes an energy absorbing component that absorbs the out of phase sum terms from the mixing devices.
Claims18
A frequency mixer, comprising:
- a set of mixing devices that generate a first sum signal and a second sum signal in response to an input signal and a drive signal such that the first sum signal is out of phase in relation to the second sum signal;
- circuit for applying the out of phase sum signals to an energy absorbing component.
A frequency mixer, comprising:
- drive signal generator that generates a first drive signal and a second drive signal that is out of phase in relation to the first drive signal;
- first mixing device that generates a first sum signal in response to an input signal and the first drive signal;
- second mixing device that generates a second sum signal in response to the input signal and the second drive signal;
- circuit for absorbing the sum signals from the first and second mixing devices.
A method for dissipating a sum signal energy in a frequency mixer, comprising the steps of:
- generating a first sum signal and a second sum signal in response to an input signal and a drive signal such that the first sum signal is out of phase in relation to the second sum signal;
- dissipating the sum signal energy by applying the out of phase sum signals to an energy absorbing component.
