Key Features
- Exceeds NSA 65-6 shielding applications
- Central plug bore accommodates ST and SMA connectors
- All connectors can be installed into a shielded enclosure while maintaining 100 dB attenuation at 18GHz
Description
 The filter has a removable center plug which is surrounded by either six or twelve waveguide bores. When the center plug is removed, connectorized cables can be inserted into the peripheral cable-sized slots. The waveguide bore diameter-to-length ratio have been optimized to ensure high attenuation.
