Abstract

The invention relates to an integrated matrix switch, comprising an LTCC circuit board, a shell, a surface laminar circuit and surface laminar devices, a power synthesizer, a gating switch and a radiofrequency signal input-output terminal. The integrated matrix switch provided by the invention solves the problems that reliability is low, size is relatively large and weight is relatively great asan external interconnection or intraconnection way is adopted due to restrictions of design forms and implementation ways in the prior art. The integrated matrix switch provided by the invention adopts an LTCC technology integrated design, eliminates connection, conversion and transition equipment among all the functional modules, greatly reduces the size and the weight, realizes highly integration and highly reliability and achieves the aims of miniaturization and light weight.

Description

technical field [0001] The invention belongs to the field of aerospace microwave technology, and in particular relates to an integrated matrix switch. Background technique [0002] The 4×2 matrix switch can be used to switch the multi-polarization working mode of the spaceborne synthetic aperture radar (SAR) or fitting synthetic aperture radar (InSAR) system, and can also be used to switch the working mode of the active phased array radar or array surface reconstruction, etc. [0003] In the active phased array radar, the switching of working modes such as main receiving signal, transmitting monitoring signal and receiving detection signal can be realized. [0004] In the SAR antenna, the single-polarization working mode and the full-polarization working mode gating of two vertically polarized (X1, X2) and two horizontally polarized (X3, X4) received signals can be realized. For example, the 4 ports of the matrix switch are connected to the 4 downlink receiving signals of ...
