Our notch filters are designed to reject one narrow band of frequencies, while letting all others pass in the operating band. They provide additional isolation by eliminating close adjacent frequencies.
The notch cavities can be cascaded or added to one another in order to sharpen the attenuation of the rejection curve. These cavities can be used individually or in multiples.
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.
- Temperature Compensation
- Ensures Frequency Stability
- High Attenuation
- Minimizes desense and interference from adjacent systems
- Adjustable Loops
- The cavity has a calibration index to reference insertion loss
