Low-loss feeder device integrating channel amplitude limiting and monitoring functions

The invention relates to a low-loss feeder device integrating channel amplitude limiting and monitoring functions, and belongs to the field of radar feed networks. The high-power microwave amplitude limiting device comprises a metal box body, an amplitude limiting printed board, a monitoring printed board and a radio frequency connector, an amplitude limiting circuit is integrated on the surface of the amplitude limiting printed board to achieve the high-power microwave amplitude limiting function of a main path, and a coupling circuit is integrated on the surface of the monitoring printed board to achieve coupling extraction of main channel signals. And the amplitude limiting printed board and the monitoring printed board are vertically mounted, so that the transmission path of a main path signal is shortened, the transmission loss of the main path is further reduced, and the miniaturization design of the structure is facilitated. According to the invention, stable amplitude limiting signal output can be mai
