SECTION 5.0
PRINCIPLES OF OPERATION
5.1 PROPER USAGE AND WARNINGS
5.1.1 Controlling Power Output
With a nominal 50 ohm resistive load and an input signal appropriate to produce a power output within
the limitations specified above, the amplifier may be placed in operation. To interrupt the output, simply
interrupt the input signal. The amplifier may be run indefinitely at rated output. Output power is usually
measured with a power meter and suitable power Termination.
5.1.2 Input Signal Levels
The Amplifier is designed to operate with less than a 0 dBm (1.0 mW) input signal.
It is not advisable to over drive any amplifier and depend on protection circuits to maintain proper gain
control.
The EMC Shop
makes available with each shipped amplifier specific data and curves so the
operator will know the proper input signal levels to more efficiently operate the amplifier refer to
Paragraph 4.7 herein.
5.2.1.1 Preamplifier
The Preamplifier provides the proper drive levels to the TWT to obtain the proper Output Power
The preamplifier is powered from a low voltage power supply that is independent of the main power
supplies.
5.2.1.2 Power Amplifier
The Power amplifier consists of the combined high power Traveling Wave Tube as the main
amplification stage. It is powered by Heater, Grid, Helix and Collector high voltage power supplies.
