A radio frequency duplexer (RF Duplexer) is a critical component in most radio systems, since it allows both receivers and transmitters to connect to a common antenna.

Whether you require components for military or civilian purposes, it's important to realize that radio frequency duplexers come in several models including Telewave, which covers 30-1200 MHz, and Base Station, which handles up to 500 watts. Some Telewave models offer over 100 dB isolation. Another type of duplexer is the mobile duplexer. When you purchase a radio frequency duplexer, you might want to:

1. Define your RF duplexer design specifications so the duplexer works symbiotically with pre-existing equipment.

2. Buy a RF duplexer from manufacturers with wide inventory choices.

3. Purchase from a radio duplexer manufacturer that is willing to work with your specialized needs.
