FUNCTION
DESCRIPTION
1Vref / Vpd
Ref. Voltage for the bias circuit. No significant amplifier current is drawn until Vref reaches
approximately 2.5V.
2VQ
The quiescent current is compensated over the temperature range.In low power mode operation (>2.0v)
the current is reduced to 50mA.The efficiency is optimized at the low RF power range (
≤16dBm).
4
RF In
RF input port connects to internally matched 50 ohm circuit.
5
Vcc1
PIN 5 connects to the driver stage HBT collector.
6
Vcc2
Vcc2 connects to the power amplifier stage HBT collector.
7, 9, 10
GND
Ground.
11
GND
Ground. This ground also serves as heat sink and must connect well to the PCB RF ground and heat
sink.
8
RF Out
RF out is internally matched to 50 ohms and expects a 50 ohm load impedance.
All supply pins may be connected together at the supply. PIN 3 N/A
