BroadBand RF Power Amplifier

Information

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.
