Embodiment Construction

[0025] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0026] like figure 1 As shown, in one embodiment, the present invention discloses a cross-backup switch network for planar integrated Ka-band of remote sensing SAR radar. The cross-backup switch network adopts complex multi-cascaded microwave ferrite switch network, changing Instead of using mechanical switches to switch the master and backup of the transmitter and receiver respectively, a ferrite switch is added between the master and backup paths to switch the master and backup, thus meeting the system requirements for t...

Abstract

The invention discloses a planar integrated Ka-band cross backup switch network for remote sensing SAR radar. The cross backup switch network includes: a microwave cavity, a ferrite switch junction arranged in the microwave cavity, and the A driver connected to the ferrite switch junction, and a load connected to the non-microwave transceiver port of the ferrite switch. By adding a ferrite switch between the main and backup paths to switch between the main and backup paths, the requirements of the system for the main and backup cross switching of the transceiver system are met. Multiple microwave functional components are manufactured in the integrated cavity to form a planar integrated Ka-band multi-cascaded microwave ferrite switch network, which reduces microwave loss, reduces component volume, improves reliability, reduces costs, and reduces Debugging link.

Description

technical field [0001] The invention relates to a ferrite switch network, in particular to a planar integrated Ka-band cross backup switch network for remote sensing SAR radar. Background technique [0002] At present, remote sensing radar system transmit and receive backup generally adopts the method of transmitting and receiving separately, that is, the main transmitter transmits, the main receiver receives, the backup transmitter transmits, and the backup receiver receives. In order to improve the reliability of sending and receiving backup, the system requires a cross backup function in addition to the main sending and receiving backup. The previous separate backup function of transmitting and receiving uses mechanical switches to switch the main and backup of the transmitter and receiver respectively. After adding the cross-backup function, the mechanical switch cannot meet the requirements, and a complex multi-cascaded microwave ferrite switch network is required. C...
