RF Limiters
The Keysight 11867A and N9355C RF Limiters protect the analyzer input
circuits from damage due to high power levels. The 11867A operates over a
frequency range of dc to 1800 MHz and begins reflecting signal levels over
1 mW up to 10 W average power and 100 watts peak power. The N9355C
microwave limiter (0.01 to 26.5 GHz) guards against input signals over
10 milliwatts up to 1 watt average power.
Power Splitters
The Keysight 11667A/B/C power splitters are two-resistor type splitters that
provide excellent output SWR, at 50 Ω impedance. The tracking between the
two output arms, over a broad frequency range, allows wideband
measurements to be made with a minimum of uncertainty.
11667A: DC to 18 GHz
11667B: DC to 26.5 GHz
11667C: DC to 50 GHz
