Mirage KP-1 Series Manual

MIRAGE KP-1 In-Shack Pre-Amplifier
General Information
This in-line GaAs-FET receive pre-amp provides high gain and low noise
amplification for weak receive signals. The pre-amp has an attenuator
built into the circuit which can be selected by changing the position of a
switch on the internal circuit board. This switch is set in the LOW level
gain position at the factory. This has been included to prevent receiver
overloading and subsequent intermodulation distortion that can come
from very strong signals. The pre-amp also has automatic RF-switching,
which disengages the pre-amp any time it detects a transmission signal
being emitted by the tranceiver.
