Abstract:
A unitarily constructed communication signal mixing and filtering device, comprising:a) an elongated vibratable mechanical resonance element having opposite clamped ends, said resonance element being constituted of an electrically insulative material, said resonance element having a first electrically conductive layer on one surface thereof and a second electrically conductive layer arranged on a second opposite surface thereof;b) means for supplying an oscillator signal (LO) to said first electrically conductive layer;c) means for supplying electrical power to said second electrically conductive layer;d) a first conductor element having an input signal (IS) supplied thereto being positioned in closely spaced relationship with said first electrically conductive layer; ande) a second conductor element being positioned in closely spaced relationship with said second electrically conductive layer, whereby said resonance element vibratingly responds to combined forces generated from an electrical interaction of the input signal (IS) and oscillator signal (LO) so as to generate an output signal (IF) definitive of a mixture of the input signal (IS) and oscillator signal (LO) and the natural frequency of vibration of said resonance element.
