The Keysight 11930A limiter provides input protection for a variety of RF and microwave instrumentation. For example, the input circuits of network analyzers may be protected for inputs up to 6 watts peak or 3 watts average power using the Keysight 11930A.

The Keysight 11930A is furnished with an APC-7 (7-mm) connector. This power limiter offers low insertion loss and linear operation at low input levels while providing protection against transients or short duration overloads.
