Microwave equipment system consists of transmitter, receiver, sky feeder system, multiplexing equipment and user terminal equipment.

The transmitter is composed of modulator, up-converter and high-power amplifier, while the receiver is composed of low-noise amplifier, down-converter and demodulator. The antenna feeder system consists of feeder, duplex and antenna. A user terminal device converts information into electrical signals. Multiplexing devices combine the electrical signals of multiple users into baseband signals that share a transmission channel. In the transmitter the modulator modulates the baseband signal to if and then up to RF, or directly to RF.

It supports PDH, SDH, Ethernet and IP services. It can well meet the bandwidth requirements of current 2G, 3G and 4G mobile services and the future commercial 5G mobile service capacity requirements.
