Communication delivers a better future

dc power splitter

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.

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;
