Description
The UTO-1025 1 watt amplifier is a
low noise figure, high dynamic range
amplifier designed to provide
broadband high power output for a
wide variety of applications. The
amplifier uses two GaAs FET stages
with active bias to simultaneously
achieve high gain, high output power
and low nDoaisteaSfighuereet4ovUe.rctohme full
military temperature range. Applica-
tions for this unique amplifier include
bench top test sets, receiver front-
end, IF gain stages and other broad-
band applications requiring low noise
and high output power. Inputs and
outputs are matched to 50 ohms for
easy intergration into new and
existing systems. Available packaging
for this unit is a hermetic TO-3 or the
connectored UCS-1P case.
