Our 6 cavity 4-inch duplexers are ideal for high power, close frequency separation installations.
These filters are designed for combining two frequencies that require extra isolation or can be used as efficient pre-selectors.
If higher levels of isolation are required, please consider using the 8 cavity configuration.
Selectivity can be determined by the field-adjustable loops.
Each cavity is temperature compensated for operation between -40ºC to +60ºC and has a gold alodine finish, silver-plated loops, and silver-plated tuning rods.
