摘要： An interdigital resonant cavity filter structure is foled to provide two adjacent chambers physically positioned side by side and electrically connected in series with each other. A center plate divides the two chambers with a slot at one end of the structure to permit the two chambers to function as one resonant cavity in a folded relation to each other. Each chamber includes interdigital resonators which are related to the overall resonant cavity to produce a band pass filter action within the folded resonant cavity. The input of the filter structure is applied through a port of a circulator connected to one end of the resonant cavity and the output is taken from another port of the circulator. The opposite end of the resonant cavity is terminated in the characteristic impedance of the resonant cavity thereby causing the overall structure to operate as a high quality notch filter.

摘要： A duplexer, useable to interlink the receiver, transmitter and antenna units of a microwave transmit/receive system takes the form of a "T" junction coupling device and three coaxial lines extending from junction ends at such device to coaxial end connectors on the ends of such lines away from such device. The "T" junction coupling device comprises a copper block having a central cavity and three bores leading into such cavity, a copper cap to close the top of such cavity, a copper disc disposed in said cavity away from its walls and containing a central space and three passages leading into said spaces and corresponding to said bores, and three brass ferrules for such lines. The ferrules are seated on the junction ends of such lines and are soldered to their outer conductors and are pressed fitted into the three bores. The inner conductors are received in the three passages in the disc and are all soldered thereto. The duplexer is free of ferromagnetic materials and contact non-linearities to forestall generation of intermodulation products. The components of the T junction coupling device and the metal parts of the end connectors are all silver plated to reduce microwave resistance losses and to prevent non-linearity due to corrosion.
