| 66-14-74 | 148-174 MHz |
Our pseudo band pass duplexer filters are designed for quick and easy installations. These filters are designed for the combination of two frequencies requiring extra isolation or can be used as efficient pre-selectors. They are available in either 4 or 6 cavity configurations if higher levels of isolation are required.
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 silver-plated tuning rods.
Every cavity is equipped with both coarse and fine tuning rods for quick and easy field or lab re-tuning.
