Novel cavity low-pass prototype power divider

Abstract

The invention discloses a novel cavity low-pass prototype power divider. The power divider comprises a shielding box, wherein one end of the shielding box is sealed, the other unsealed end of the shielding box serves as a power input end, through-holes are arranged on an upper surface of the sealed end of the shielding box and a lower surface of the sealed end of the shielding box respectively and serve as a first power output end and a second power output end, a joint is respectively installed at the power input end, the first power output end and the second power output end, a power distribution joint with three interfaces is arranged between the joint of the first power output end and the joint of the second power output end, the upper interface and the lower interface of the power distribution joint are connected with the joint of the first power output end and the joint of the second power output end respectively, a plurality of second impedance transformers are connected between the third interface of the power distribution joint and the joint of the power input end, and the plurality of second impedance transformers are connected with each other through impedance matching joints. The power divider has the advantages of being flexible, capable of eliminating system mismatching phenomena, convenient for establishment of communication networks and the like.

Description

technical field [0001] The invention mainly relates to the communication field, in particular to a novel cavity low-pass prototype power divider. Background technique [0002] The full name of the power divider is the power divider, and the English name is Power divider. It is a device that divides the energy of one input signal into two or more outputs with equal or unequal energy. It can also conversely synthesize the energy of multiple signals into one output. It can also be called a combiner. A certain degree of isolation should be guaranteed between the output ports of a power divider. The main technical parameters of the power splitter include power loss (including insertion loss, distribution loss and reflection loss), voltage standing wave ratio of each port, isolation between power distribution ports, power capacity and frequency bandwidth, etc. Existing power splitters are prone to system mismatch. Contents of the invention [0003] The purpose of the pres...
