  • 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.

  • Questions & Answers
    1. Hello there,

      We have a comprod duplexer. The frequency response does not respond to one of the rod, we suspect something has broken in it. I am hoping to remove the rod from the can. Is there a good way of taking apart the can?
