V. 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.
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 product
specification for details). Higher-than-rated drive power may destroy
transistors and VOID ANY WARRANTY.
SUPPLY VOLTAGE:
The maximum operating voltage is 15.0VDC. When using a 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.
CASE TEMPERATURE
High power can mean high temperatures. Mount the amplifier where air
can freely circulate into the cooling fan and where clothing, blankets, etc.
will not accidentally be placed over it.
TERMINATIONS
The efficiency of this amplifier will degrade if it is operates into anything
but a 50 Ω load. Lowered efficiency may mean any or all of the following:
lower power output, increased current drain, higher operating
temperature and reduced lifetime.
