Monolithic single and double sideband mixer apparatus

摘要

A monolithic mixer which is impedance matched to a fundamental waveguide, utilizes a slot coupler and a coplanar transmission line to apply an RF and local oscillator signal to a Schotty-barrier diode. The dielectric substrate is utilized to create a dielectric surface wave resonance which is utilized by centering a slot coupler with respect thereto, to provide a reactive image termination at the upper sideband and thereby enhance single and double sideband mixer operation. The IF signal which is available at the output of the Schottky-barrier diode is filtered by means of an RF bypass capacitor that is located on the dielectric substrate surface.
