Abstract
A simplified, compact, flat microwave frequency converter assembly utilizes a flat quad diode bridge, and has two pairs of opposed flat conductors, each with a respective one of the opposed conductors on a respective side of a flat dielectric substrate . Each of the pair extends orthogonally from their intersection at the bridge. The bridge is connected at opposite corners thereof to adjacent ends of the conductors at the intersection on a first side of the substrate. These first-side conductors are in electrical continuity with a conductive layer extending about the periphery of the substrate on the first side thereof. This layer is, in turn, in contact with a conductive carrier plate by means of which the layer is grounded. On the second side of the substrate, each of the pair of capacitors affixed to the substrate is connected between respective opposite corners of the bridge, and the adjacent ends of the conductors of one of said pairs. In this manner, two pairs of input baluns are provided to accept, for example, an input RF signal, and a local oscillator signal. An output conductor pair is provided, each extending outwardly on the substrate first face from one of the bridge o…
