Antenna duplexer suitable for ultrashort wave radio station under tdma network

Abstract

The present invention provides a kind of antenna sharer applicable to the ultrashort wave radio station under the TDMA network, comprising: a control module, a path selection module, a receiving module; the control module includes: an FPGA module and a CPU module; the path selection module includes: 10 channels 2 to 1 transceiver switch TX / RX, a group of 10 to 1 switch groups and related drive circuits; the receiving module includes: protection circuit, BPF filter, one-to-two power divider, limiter circuit, low-noise amplifier and a Divide into six power dividers. In the design of the present invention, signal attenuation and radio frequency interference between channels are fully considered, and it will not affect the original indicators of the radio station. The device of the present invention has good electromagnetic compatibility, and is not affected by weapon systems or other natural environments, nor Interfere with other weapon systems.

Description

technical field [0001] The invention belongs to the technical field of ultrashort wave radio stations, and in particular relates to an antenna sharer suitable for ultrashort wave radio stations under a TDMA network. Background technique [0002] During the simulation and verification tests of the communication system and command system in the army base, due to the limitation of the site and funds, it is impossible to equip the vehicles and radio stations according to the actual establishment of the army to carry out the communication system test that is completely consistent with the actual installation of the army. Consistent communication networking effect, usually the number of radio stations will be roughly the same as the actual installation of the army, and the communication vehicles will be greatly reduced due to funding and site constraints, resulting in a vehicle that may be equipped with more than a dozen ultrashort wave radio stations. In theory, each ultrashort wa...

[0002] During the simulation and verification tests of the communication system and command system at the army base, due to the limitation of the site and funds, it is impossible to equip the vehicles and radio stations according to the actual establishment of the army to carry out the communication system test that is completely consistent with the actual installation of the army. Consistent communication networking effect, usually the number of radio stations will be roughly the same as the actual installation of the troops, and the communication vehicles will be greatly reduced due to funding and site constraints, resulting in a vehicle that may be equipped with more than a dozen ultrashort wave radio stations. In theory, each ultrashort wave radio station The radio station needs to be equipped with an antenna, which is generally installed on the roof of the car, which greatly increases the difficulty of the layout of the roof antenna and the mutual interference between the antennas
