500W HF Linear Amplifier Unit

Input Voltage: 28 VDC

Power Output: 1.6-30MHZ: 500W PEP and average

The power amplifier is fully protected by microprocessor control. This circuitry dynamically

monitors all amplifier parameters, and provides adjustments and protection against high VSWR,

under voltage, over current and high temperature conditions.

Current- protection against over current condition (exceeding 60 amps) and current imbalance

between amplifier modules (exceeding 20%). When one of these two conditions exists, the amplifier

turns off-line. To reset the transceiver, power down the amplifier and restart the unit.

Volt - protection against under amplifier turns off-line. To reset the transceiver, power down the

amplifier and restart the voltage condition (less than 28+/-3 VDC). When this condition exists, the

unit.

VSWR –when a sampled VSWR exceeded 4:1 and the power reflected back to the amplifier is

higher than acceptable, the amplifier turns off-line. To reset the transceiver, power down the

amplifier and restart the unit.

Temp - protection against over temperature condition

Atten –as input RF power level increases beyond 60-70 watts, the attenuation increases

automatically. The Attenuate remains engaged until the input drops to 30 watts.

ALC Control- provides adjustable ALC feedback voltage.

A positive voltage is present on the Amplifier line for use with the equipped transceiver for ALC

input control.

PTT keying mode and Band input filter selection enabled automatically. Band switching time is

typically 100 msec or less.

This automated capability is ideal for remote or unattended operating site application.
