Drop-In Isolators

High Power (HP)

High-power drop-in isolators serve as vital components in aerospace applications, where they play a key role in safeguarding sensitive electronic equipment from excessive power levels and managing signal reflections. These isolators efficiently isolate and redirect reflected signals away from their source, ensuring uninterrupted and reliable operation in high-power aerospace systems.

High Power (HP)

All catalog part numbers are for devices with clockwise rotation, however, counter-clockwise rotation is available by request. Consult the factory for special performance and unique mechanical configurations. We have many other designs no listed in the catalog, and develop new designs on a frequent basis.

Encapsulation is available on some designs for high peak power & high altitude capability.

Low IMD Designs: See Note 14

Note 1:  BeO Termination
Note 12:  Encapsulated for High Peak Power
Note 14:  -80 dBc IMD with 2 Tones at 20W

W = Watts

*  Case Temperature Not To Exceed Operating Temperature
