Broadband Preamplifiers and Power Amplifiers
Preamplifiers and power amplifiers can be used with your spectrum analyzer to
enhance measurements of very low-level signals.
— The Keysight 8447D preamplifier provides a minimum of 25 dB gain from
100 kHz to 1.3 GHz.
— The Keysight 87405B preamplifier provides a minimum of 22 dB gain from
10 MHz to 4 GHz. (Power is supplied by the probe power output of the
analyzer.)
— The Keysight 83006A preamplifier provides a minimum of 26 dB gain from
10 MHz to 26.5 GHz.
— The 11909A low noise preamplifier provides a minimum of 32 dB gain from 9
kHz to 1 GHz and a typical noise figure of 1.8 dB.
RF and Transient 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.
The Keysight 11947A Transient Limiter protects the analyzer input circuits from
damage due to signal transients. It specifically is needed for use with a line
impedance stabilization network (LISN). It operates over a frequency range of 9
kHz to 200 MHz, with 10 dB of insertion loss.
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
