The Model 411 LA is a general purpose broadband amplifier capable of more than 10 watts of linear power output when driven by any laboratory signal or sweep generator from . 15 to 300 MHz. An ultra linear Class A design, the 411LA will “boost” the output of any signal source by a flat 40 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, FM, SSB, CATV, pulse and other complex modulations. Although specified only over the . 15 to 300 MH frequency range, full power output is typically available from . 12 to 320 MHz. The use of microw'ave transistors on thin film substrates, microstrip circuitry, and plug-in modules make the 411LA both reliable and easy to service. An integral power supply and cooling system permit operation over a wide range of temperature and AC line conditions.
