I. PRODUCT DESCRIPTION

The PA3-1XC model is a VHF RF power amplifier series intended for use in the
mobile applications. This amplifier can deliver RF power from 15 to 60 W when
driven with 1 to 10 W (model dependant) and it will cover the frequency range
from 136 - 174 MHz. The mobile amplifier is designed to be installed in the
interior of a car or in the trunk. The amplifier’s dimensions are: 9.5”L x 3.0”H x

4.5” W (see figure 1) and the weight is 4 lbs.

NOTES:

1. The rated output power of this amplifier is for single carrier operation.
For situations when multiple carrier signals are present, the rating would
have to be reduced by 3.5 dB, especially when the output signal is re­radiated and can cause interference to adjacent band users. This power
reduction is to be by means of input power or gain reduction and not by
an attenuator at the output of the device.

OPERATING VOLTAGE:

Nominal DC operating voltage is 13.8VDC and the specifications are given
at this voltage, as measured at the DC input connector. Reduced DC input
voltage will result in lower output power and efficiency.

EIA DUTY CYCLE:

NOTE: Use of TPL Mobile Amplifiers above the recommended duty cycle

or in repeater applications is not recommended and voids the warranty.

CONFIGURATION:

All mobile amplifiers are supplied with Solid State Carrier Operated
Relay (SSR).
