Informationen:
                                    The Model 420LA is a general purpose broadband amplifier
capable of more than 20 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 42ÖLA will “boost" the
output of any signal source by a fiat 45 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 MHz frequency range, full
power output is typically available from .12 to 310 MHz.
The microwave transistors on thin film substrates,
microstrip circuitry, and plug-in modules make the 420LA
both reliable and easy to service. An integral power supply
and coohng system permit operation over a wide range of
temperature and AC line conditions.
