Antenna sharing device suitable for ultra-short wave radio station in TDMA network

The invention provides an antenna sharing device suitable for an ultra-short wave radio station under a TDMA network. The antenna sharing device comprises a control module, an access selection moduleand a receiving module, the control module comprises an FPGA module and a CPU module. The access selection module comprises 10 paths of one-out-of-two transmit-receive switches TX/RX, a one-out-of-tenswitch group and a related drive circuit. The receiving module comprises a protection circuit, a BPF filter, a one-to-two power divider, an amplitude limiting circuit, a low noise amplifier and a one-to-six power divider. In the design, signal attenuation and radio frequency interference among all paths are fully considered, original indexes of a radio station are not affected, and the device hasgood electromagnetic compatibility, is not affected by a weapon system or other natural environments and does not interfere with other weapon systems. 本发明提供了一种适用于超短波电台在TDMA网络下的天线共用器，包括：控制模块、通路选择模块、接收模块；所述控制模块包括：FPGA模块和CPU模块；通路
