Description

The AM-1077 is an RF power amplifier designed to boost the output power of the PRC1077 transceiver from 5W to 50W in the 30 MHz to 87.975 MHz frequency range and can be used in mobile and fixed base applications. The AM-1077 integrates with the PRC1077 by automatically responding to RF input signals when the amplifier is turned on. The AM-1077 also works with the AN/PRC-77 or equivalent transceiver.

The AM-1077 is encased in a rugged, lightweight, shock resistant, moisture proof chassis.

The AM-1077 includes the following features:

  • 50W output power
  • 30 MHz to 87.975 MHz frequency range
  • Harmonic filter switching
  • PTT keying
