We offer a variety of cavity duplexers for major cellular bands. They can be used as accessories to our own base station products, as well as with third-party base station products or SDR based systems.
Cavity duplexers offer excellent performance compared to discrete duplexers built from electronic components or even SAW filters:
- very low insertion loss (typically <= 1.0 dB), ensuring most of your intended signal actually passes through
- very high attenuation of any frequencies outside the respective Rx and Tx bands
- large isolation between Rx and Tx, protecting the sensitive Rx input from being overdriven with the relatively high power Tx signal.
sysmocom offers mainly two families of duplexers: Either rated up to 30W RF power for use in dry environment (-kt30 suffix) only, or with IP67 rated weather-proof enclosure for outdoor (-kt40-ip67 suffix).

The table below shows our standard models, most of which we typically keep in stock in low quantity. Non-stock parts require an average or 4-5 weeks of production lead time.
custom duplexer models
We are very happy to produce cavity duplexers per our customer request. Customization includes bands / frequency, connectors / RF pwerformance parameters. Please reach out to firstname.lastname@example.org with your requirements. We can produce custom duplexers in low quantities (absolute minimum 10 units), but not at MOQ-1. Thanks for your understanding.
