OPERATING PRECAUTIONS
CAUTION:
This amplifier produces RF voltages that can cause painful and dangerous burns. Use caution!
Connect and disconnect all RF connections with the drive power and DC power off.
Connect and disconnect all RF connections with the drive power and DC power off.
DRIVE POWER:
RF power transistors, although quite rugged in most respects, are easily damaged by
overdrive. Be careful not to overdrive the amplifier even momentarily (before applying any
drive signal please check table I for details). Higher-than-rated drive power may destroy the
transistors and VOID ANY WARRANTY.
overdrive. Be careful not to overdrive the amplifier even momentarily (before applying any
drive signal please check table I for details). Higher-than-rated drive power may destroy the
transistors and VOID ANY WARRANTY.
SUPPLY VOLTAGE:
The maximum operating voltage is 15VDC. When using the DC power supply make sure
that it is not adjusted above 15 volts. If it is possible for the voltage to go above 15 Volts for
any reason, including failure of the power supply, install a “crowbar” circuit to prevent damage
to the amplifier in the event of excess voltage.

any reason, including failure of the power supply, install a “crowbar” circuit to prevent damage
to the amplifier in the event of excess voltage.
CASE TEMPERATURE:
High power can mean high temperatures. Mount the amplifier where air can freely circulate
over it and where clothing, blankets, etc. will not accidentally be placed over it. Keep duty
cycle below limits.
over it and where clothing, blankets, etc. will not accidentally be placed over it. Keep duty
cycle below limits.
TERMINATIONS:
The efficiency of this amplifier will degrade if it is operated into anything but a 50 Ù load.
Lowered efficiency may mean any or all of the following: lower power output, increased
current drain, higher operating temperature, and reduced life time.
