The 2645240 Series of EMR amplifiers are
intended for use in low power amplification and re-
amplification systems. Applications include land
mobile radio bi- and uni- directional signal booster
systems. They will cover the frequency range
extending from 440 MHz to 470 Mhz.
For operator convenience, views of the top,
from; and side of the amplifier are presented here.

The 264524C Series amplifier is a self-contained
single board unit capable of up to 6 watts of output
power with built in power control circuitry. The input
signal is amplified by 2 gain blocks and a module
capable of 65dB of gain, filtered by the output low
pass filter and finally analyzed by the output coupler
circuitry for excessive power. if overdrive level is
sensed, the coupler and power control circuits
compute a dc voltage that controls on electronic
attenuator at the input of the unit. The attenuator
makes the necessary adjustment to relieve the
overdrive condition sensed by the output coupler.
