UHF Cavity Combiner

Point frequency combiners are widely used in relay stations of general communication networks and various private and public mobile communication networks. The point frequency combiner can connect 2~16 base transmitters to one transmitting antenna. This not only saves the engineering costs of antenna, feeder and tower erection, but more importantly, because this product uses a high O cavity And components such as ring isolators can better suppress the out-of-band noise and high-order harmonics of the transmitter, improve the purity of the transmission spectrum, and fundamentally improve the intermodulation interference problem that is difficult to solve in multi-antenna installations.

Various customized frequencies are available, with features such as low temperature drift, low insertion loss, low intermodulation, and high isolation.

Note:

1. It is recommended that the channel spacing be greater than 250K, otherwise the standing wave of some antenna ports may exceed 1.8;

2. The above indicators are formulated based on the interval ≥ 250KHz. If the interval is 150 KHz ≤ interval ≤ 250KHz, some indicators will be affected; if the interval is less than 150K, the channel interval cannot be combined;
