The frequency combiner is widely used in relay stations of various communication networks and is also suitable for various public and private mobile communication networks. This device can connect 2 to 16 base station transmitters to the same transmitting antenna. As a result, it not only saves the cost of constructing antennas, feeders, and base station towers, but more importantly, since the device uses high-Q resonant cavities and ring isolators among other components, it can effectively suppress out-of-band noise and higher-order harmonics generated by the transmitters, thereby improving the purity of the transmitted signals. It fundamentally solves the intermodulation interference problems that are difficult to address in multi-antenna systems.

There are multiple customizable frequency options available, and these frequency solutions have the advantages of low temperature drift, low insertion loss, minimal intermodulation interference, and high isolation.

Advantages:

Main frequency bands: 136-174MHz / 330-520MHz / 851-869MHz

Temperature drift and power drift <20kHz

Insertion loss for all four channels across the full temperature range is less than 3.0 dB

Input VSWR is less than 1.3

PIM < -140dBc @ 2*43dBm

The product has a high power output capability of 200 watts or more.

Tuning range: 2 MHz for VHF bands, 5 MHz for UHF bands

Regardless of the number of channels and frequencies, the product can be customized according to customer requirements.
