Agilent / HP 491C
TWT Amplifier
Description
The Agilent 491C is a TWT Amplifier.
The 491C TWT Amplifier covers the 2 to 4GHz frequency range with 1 W output and 30 dB gain.
Input/output impedance is 50-ohms, type N female connectors.
Sensitivity: modulation input of >-20 V peak reduces RF output by >/=20 dB from DC to 50 kHz.
<
p>Frequency response is DC to 500kHz (3 dB), pulse response is <1 µs rise and fall times.
Features include front-panel gain adjust, cathode current meter, and modulation input.
