NOTES: All specifications guaranteed -54 to +85°C.
Please contact the factory for other frequencies, noise figures, and gain options. See page 59 for outline.
In any solid state amplifier, both the gain and the
noise figure will vary as a function of temperature.
The overall gain of an uncompensated amplifier tends
to decrease as the base plate temperature increases,
while the noise figure will exhibit the opposite effect
and increase as the temperature rises. The amount
of change in gain is directly proportional to the num-
ber of stages in the device, the operating frequency,
and the way the individual stages have been biased.
In order to reduce this variation, it is often necessary
to temperature compensate the amplifier.
