Problems solved by technology
Among the existing RF coaxial switches, there is a single-pole ten-throw coaxial switch, which is composed of a relay system and a microwave transmission system. Since the shape of the transmission reed in the microwave transmission system cannot match the transmission line impedance well, the existing single-pole The ten-throw coaxial switch, whose microwave transmission frequency can reach up to 18GHz, cannot realize higher frequency microwave signal transmission, and cannot meet the development needs of test and measurement instruments in higher frequency bands

The invention discloses a high-frequency microwave transmission system and a single-pole ten-throw coaxial switch. The microwave transmission system is composed of ten microwave signal transmission paths, wherein one microwave signal transmission path includes a transmission cavity and a cover plate connected together; A transmission reed that can move up and down is installed on the inner side of the cover, and the push rod passes through the return spring and the cover at the same time, and is put into the hole in the middle part of the transmission reed; the two ends overlapping with the transmission reed are provided with an intermediate radio frequency coaxial Connector and external RF coaxial connector; one end of the overlap between the transmission reed and the inner conductor of the intermediate RF connector adopts a triangular structure, and the other end of the overlap with the inner conductor of the outer RF connector adopts a step change method of narrowing width , the middle part is provided with a circular compensation hole riveted with the push rod to match the transmission line impedance and ensure that the transmission frequency of the microwave transmission system can reach 26.5GHz.
Description
technical field [0001] The invention belongs to the field of microwave passive devices, in particular to a high-frequency microwave transmission system and a single-pole ten-throw coaxial switch. Background technique [0002] As a microwave passive device, the RF coaxial switch mainly realizes the transmission and switching of microwave signals, and is widely used in automatic test systems, radar and communication fields. Among the existing RF coaxial switches, there is a single-pole ten-throw coaxial switch, which is composed of a relay system and a microwave transmission system. Since the shape of the transmission reed in the microwave transmission system cannot match the transmission line impedance well, the existing single-pole The ten-throw coaxial switch, whose microwave transmission frequency can reach up to 18GHz, cannot realize higher frequency microwave signal transmission, and cannot meet the development needs of test and measurement instruments in higher frequenc...
