1. General Information.
The power amplifier (PA) is nonlinear AB to C class unit that is intended for frequency (phase)
modulated (manipulated) signals amplification.
modulated (manipulated) signals amplification.
There is the fan for forced cooling. The automatic power control loop keeps the output power at the
rated level. It reduces this level, when the load VSWR is above 2, when the heatsink temperature
exceeds +85ºC or under the outer control.

2. Installation Guide.
Unit is intended for a rack installation in a standard 19” cabinet, where it requires 4U high slot. The
installation shall provide a proper air access to the unit; no obstacle for air is allowed closer than 3”
from fan and air exits.

from fan and air exits.
Copper wires # 10 AWG shall be use in DC power line. Wires shall be crimped to ring terminals
3. Operation Guide
- The power supply voltage should be in the limits 46.5 – 49.5 V;
- Do not apply RF signal out of rated 220-222 MHz frequency range:
- For transmitting the input RF power should be in the range 1…4 W.
- Do not destroy the sealing and other labels.
- Do not apply RF signal out of rated 220-222 MHz frequency range:
- For transmitting the input RF power should be in the range 1…4 W.
- Do not destroy the sealing and other labels.
Green LED “DC ON” shines, if the power supply voltage is applied to the unit.
The fan rotates, when the rated RF signal is present at the input.
Red LED “LOW OUT” goes on, if the output power fails to more than 1 dB below the rated level.
It may indicate a problem inside the unit. Be sure that the power supply voltage and input power are
in the allowed limits.

Red LED “HIGH VSWR” goes on, when the load VSWR is greater than 2 – 2.5.
Red LED “HIGH TEMP” goes on, when the heatsink temperature exceeds +85ºC.
