Problems solved by technology

In order to be compatible with these two polarization methods, the portable satellite communication terminal must install the related radio frequency modules and waveguide components according to the antenna horizontal polarization waveguide interface and vertical polarization waveguide interface. If the user replaces the service satellite and the polarization mode Changes, it is necessary to adjust the horizontal polarization waveguide interface, vertical polarization waveguide interface RF module, waveguide components and other modules, this adjustment is not easy for equipment manufacturers or users, time-consuming and labor-intensive

Description

technical field [0001] The invention belongs to the technical field of satellite communication line polarization transceiver, in particular, relates to a satellite communication transceiver polarization switching control device. Background technique [0002] Existing technology In the field of satellite communication technology, the integrated satellite communication terminal products using flat-panel antennas are highly integrated installations of antennas, radio frequency transceiver modules, MODEMs, satellite controllers, power management modules, and servo mechanisms, because there are many integrated modules and wires. The cable routing is complicated, and the available internal space is very limited, making it difficult to integrate other functional finished modules. [0003] And in satellite communication products that adopt linear polarization, the transmitting and receiving beams are divided into horizontal receiving and vertical transmitting, or two polarizations o...
