- 17 - Abstract Simplified Double Balanced Frequency Converter 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 inter- section 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 ex- tending 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 sub- strate first face from one of the bridge opposite corners to terminals between the bridge and con- ductive layer, each then continuing on the second face from the terminals to a junction adjacent the substrate edge, and serving as an output from which a heterodyned signal may be obtained.
