Frequency combiner is widely used in general communication network relay stations as well as various dedicated and public mobile communication networks. The frequency combiner can connect 2 to 16 base station transmitters to the same transmitting antenna, which not only saves the engineering costs of antennas, feeders, and towers, but more importantly, this product adopts high-Q cavities and ring isolators, which can better suppress the out-of-band noise and high-order harmonics of the transmitter, improve the purity of the transmitted spectrum, and fundamentally solve the intermodulation interference problem that is difficult to address with multiple antenna installations.

The product supports multiple customizable frequencies and features low temperature drift, low insertion loss, low intermodulation, and high isolation.
