Introduction

This diplexer series is designed for applications in satellite reception systems to combine or separate two different signal bands.

For example to combine or separate C band / Ku Band or Hi Band / Low Band.

This diplexer offers you low insertion loss, high rejection and a good return loss. Apart from the excellent electronic specifications, it boasts a high quality die-casting housing with high RFI shielding effectiveness.

In addition to the general models in the table below, the satellite-IF bands can be designed according to customer specifications.

For more diplexer products, please see our diplexer category.
