Our pass reject filters are designed to pass a frequency band and reject a narrow band of frequencies. They provide more attenuation than our standard band pass type cavities.
These cavities can reject frequencies on either the high or low side of the pass frequency.
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.
