Abstract
A dual in-situ mixing approach for extended tuning range of resonators is described. In one embodiment, a dual in-situ mixing device tunes an input radio-frequency (RF) signal using a first mixer, a resonator body, and a second mixer. In one embodiment, the first mixer is coupled to receive the input RF signal and a local oscillator signal. The resonator body receives the output of the first mixer, and the second mixer is coupled to receive the output of the resonator body and the local oscillator signal to provide a tuned output RF signal as a function of the frequency of local oscillator signal.
Claims1
An apparatus, comprising:
- a resonator body;
- a first non-linear mixer coupled to the resonator body, the first non-linear mixer to receive a frequency of an radio-frequency (RF) input signal and a frequency of a local oscillator signal as input frequencies, wherein the output of the first non-linear mixer is coupled to a driving electrode of the resonator body;
- and
- a second non-linear mixer coupled to a sensing electrode of the resonator body, the second non-linear mixer to receive a frequency of the resonator body and the frequency of the local oscillator signal as input frequencies, wherein the output of the second non-linear mixer is an RF output signal having a tuned frequency as a function of the frequency of the local oscillator signal.
