BROADBAND POWER AMPLIFIER
Information
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.
