Maximise base station investment

Active & passive RF solutions

Custom combiners


Filtronic offers a range of custom combiner products for both in-band and cross-band applications. An RF combiner acts as a transmission component, combining the power between two or more ports. Our expertise lies in highly complex applications, such as combiners with a very small guard band, minimising loss of usable spectrum. This is critical as we move towards 5G and dynamic TDD (Time Division Duplex), using the same frequency to transmit and receive.

We work closely with the OEMs and the operators to offer them a solution which enables them to make best use of their base station investment. Our aim is to offer the products with highest-in-class performance while keeping the cost and weight down by using our proprietary approach.


  • Patented designs and proven track records
  • Very narrow guard band, low insertion loss and high isolation to minimise the total effect on the combined signals and to preserve valuable spectrum.
  • Range of standard and custom in-band combiners for different frequency bands and for multiple technologies
