Ideal for high power, close frequency separation installations
- Designed for combining two frequencies that require extra isolation. Can also be used as efficient pre-selectors
- Temperature compensated to ensure frequency stability
- High attenuation to minimize desense and interference from adjacent systems
- Adjustable loops
Description
Our 4 cavity 4-inch cavity duplexers are ideal for high power, close frequency separation installations. These filters are designed for combining two frequencies or can be used as efficient pre-selectors. If higher levels of isolation are required, please consider using 6 cavity configurations. Selectivity can be determined by the field-adjustable capacitors. Each cavity is temperature compensated for operation between -40ºC to +60ºC and has a gold alodine finish, silver-plated loops, and plated tuning rods.
