The Model 5100L is a general purpose broadband amplifier capable of more than 100 watts of linear power output when driven by any laboratory signal or sweep generator from 1,5 to 400 MHz. An ultra linear Class A design, the 5100L will "boost" the output of any signal source by a fiat 50 dB (±1.5 dB) and provide its full forward output power into any load impedance (from an open to a short circuit). Its output is a faithful reproduction of the input waveform for AM, FMr SSB, CATV; pulse and other complex modulations. Although specified only over the 1.5 to 400 MHz frequency range, full power output is typically available from 1 to 410 MHz. The use of stud mounted UHF transistors on microstrip circuit boards makes the 5100L both reliable and easy to service. An integral power supply and cooling system permits operation over a wide band of temperature and AC line conditions.
