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.
