The Model 406L is a broadband solid state power amplifier
covering the frequency range of 150 KHz to 250 MHz.
Over 5 watts of RF power can be produced at the output, with
low harmonic and intermodulation distortion. A highly linear
Class A design, the Model 406L will amplify inputs of AM,
FM, SSB, pulse and other complex modulations, with minimum
distortion. The 40 dB gain of the unit permits it to be
driven to its full power output by any signal or sweep
generator capable of supplying a minimum -3 dBM (.15 volts
RMS) signal level into its 50 ohm input. Virtually all
commercial signal and sweep generators are capable of
supplying this signal.
The Model 406L operates over its entire bandwidth without
tuning or other adjustments. It is capable of supplying
useful power output up to 270 MHz, at reduced gain.
The unit is unconditiona1ly stable and will not oscillate
for any possible combination of source and load impe-
dances. It is protected against failure due to output load
mismatch and/or overdrive. The Model 406L will withstand a
+16 dB overdrive (input signal of 1 volt RMS) for all output
load conditions including both short and open circuit loads.
Output RF voltage level, as well as power output into 50
ohms, is monitored by a front panel meter. An integral power
supply permits operation directly from the AC line.
