11930A/B Power Limiters
技术概述
dc to 6 GHz, 5 MHz to 6 GHz
- high power protection
- exceptional return loss
Increased power protection
The Keysight Technologies, Inc. 11930A/B limiters provide 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 11930A. The 11930B provides the same protection to spectrum analyzers and sources. At even greater power levels, failure mode for the limiter is either an open circuit or a short circuit to ground, thereby protecting the instrument from damage.
Excellent accuracy
The 11930A is furnished with an APC-7 connector and the 11930B has a type-N connector. These limiters offer low insertion loss and linear operation at low input levels while providing protection against transients or short duration overloads. In Figure1, typical data for output power versus input power is shown for the 11930A/B. Figures 2 and 3 illustrate typical insertion loss and return loss.
