Description: BROADBAND POWER AMPLIFIER
Information:
                                    The Model 603L is a general purpose broadband amplifier
capable of more than 3 watts of linear power output when
driven by any laboratory signal or sweep generator from .8
to 1000 MHz.
An ultra linear Class A design, the 603L 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 .8 to ίΟΟΟ MHz frequency range, full
power output is typically available from .7 to 1020 MHz.
The use of stud mounted microwave transistors on a
microstrip circuit board makes the 603L both reliable and
easy to service. An integral power supply permits operation
over a wide range of temperature and AC line conditions.
