DBS Band 2 Port TX/RX Circular Polarization Diplexer Description

DBS, or Direct Broadcasting Satellite Service, usually refers to the use of geosynchronous orbit satellites to radiate a certain area on the ground with high power, and transmit TV entertainment information to family units, benefiting the majority of users.

Compared with traditional communication satellites, live broadcast satellites have the following characteristics: satellite wave speed is narrow, only covering a certain country or region; satellite radiation power is large, generally EIRP (equivalent isotropic radiated power) is greater than 48dBw; user antennas are small and large in number, Typical receiving antenna diameter D = (0.5 ~ 1.0) m, low cost.
