Informationen:
                                    The Model 300L is a broadband solid state power amplifier,
covering the frequency range of 250 KHz to 110 MHz.
Three watts of RF power can be produced at the output, with
low harmonic and intermodulation distortion. The amplifier
will accept inputs of AM, FM, SSB, Pulse and other complex
modulations, over its entire frequency range. 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 -5 dBM (.13 volts) signal level into its 50 ohm
input. Virtually all commercial signal and sweep generators
are capable of supplying this signal.
The Model 300L operates over its entire bandwidth without
tuning or other adjustments. It is capable of supplying
useful power output up to 150 MHz, at reduced gain.
It is unconditionally stable and will not oscillate for any
possible combination of source and load impedances. This
feature is especially useful where highly reactive loads are
encountered. Reflected power due to output load mismatch is
absorbed in the amplifier.
The Model 300L is protected against failure due to output
load mismatch and/or overdrive. The unit will withstand a
+20 dB overdrive (input signal of +15 dBM), for all output
load conditions including both short and open circuit loads.
