Ceramic Duplexers

Ceramic duplexers are commonly used in FDD (Frequency Division Duplexing) applications to separate the downlink and uplink signals to/from the antenna.

A key performance metric used in the selection of the duplexer is the degree of rejection.  Our duplexers can provide up to 70 dB of attenuation, as well as insertion loss below 1 dB, and power rating up to 60 watts.

FAQ about Ceramic Duplexers

What is a ceramic duplexer and how does it work?

A ceramic duplexer is a compact RF component that separates transmit and receive signals, allowing both to share a single antenna. It uses ceramic resonators based on piezoelectric principles to provide frequency selectivity and isolation between channels.

What are the advantages of ceramic duplexers?

Ceramic duplexers are small, lightweight, and cost-effective. They offer good isolation and stable performance, making them ideal for space-constrained applications such as mobile devices, GPS units, and compact communication systems.

What frequency ranges do ceramic duplexers typically support?

They are generally designed for UHF and microwave frequency bands, often ranging from a few hundred MHz up to several GHz, depending on the application.

Where are ceramic duplexers commonly used?

Ceramic duplexers are widely used in wireless communication devices, cellular base stations, GPS receivers, and any system that requires duplex operation in a compact footprint.

What are the limitations of ceramic duplexers?

While efficient and compact, ceramic duplexers typically have lower power handling and isolation than cavity duplexers. They may also be more sensitive to temperature variations and mechanical stress.
