VHF 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.


Advantage:

Main frequency band 136-174MHz/330-520MHz/851-869MHz

Temperature drift and power drift<20Khz

Four-way full-temperature environment insertion loss <3.0dB

Input standing wave <1.3

PIM<-140dBc@2*43dBm

Product capability of high power 200W and above

Tuning range: 2MHz@VHF/5MHz@UHF

Products with any number of channels and frequencies can be customized according to customer needs

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;
