Revision J
PIN
FUNCTION
DESCRIPTION
1
Vcc1
PIN 1 connects to the driver stage HBT collector.
2
RF In
RF input port connects to internally matched 50 ohm circuit.
3Vref / Vpd
Ref. Voltage for the bias circuit. No significant amplifier current is drawn until
Vref reaches approximately 2.5V.
4
Vcc2
Vcc2 connects to the power amplifier stage HBT collector.
5
RF Out
RF out is internally matched to 50 ohms and expects a 50 ohm load impedance.
6
GND
Ground
7GND
Ground. This ground also serves as heat sink and must connect well to the PCB
RF ground and heat sink.
All supply pins may be connected together at the supply.
