FIGURE 2
DC CONNECTOR WIRING
Attach DC input wires
in accordance with this
diagram. If the wires
are too large for the
holes, solder them to the
sides of the blade.
OPERATING PRECAUTIONS
CAUTION: This amplifier produces RF voltages that can cause pain-
ful and dangerous RF burns. Use caution! Connect and disconnect
all RF Connections iwth the DC power and drive power off.
DRIVE POWER: RF power transistors, although quite rugged in most
respects, are easily damaged by overdrive. Be careful not to over-
drive this amplifier, even momentarily. Higher than rated power drive
may destroy transistors and VOID THE WARRANTY.
SUPPLY VOLTAGE: The maximum operating voltage is 15 Volts
DC. When using an AC power supply, make sure that its output
voltage is not adjusted above 15 Volts DC. If it is possible for the
voltage to go above 15 Volts DC for any reason, including failure of
the power supply, install a “Crowbar” unit. This will 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 accidently be placed over it. Keep
duty cycle below limits.
TERMINATIONS: The Amplifier parameters will degrade if it is oper-
ated into anything but a 50 Ohm load. That may mean any, or all of
the following: lower power output, increased current drain, higher
operating temperature, lower efficiency and reduced lifetime.
