UMTS-band 4W HBT Amplifier Module
Evaluation Board Bias Procedure
The following bias procedure is recommended to ensure proper functionality of AP622 in a laboratory environment. The sequencing is not
required in the final system application.
5V GND
28V
28V
Turn-on Sequence:
1. Attach input and output loads onto the evaluation board.
2. Turn on power supply Vcc = +28V.
3. Turn on power supply Vpd = +5V.
4. Turn on RF power.
Turn-off Sequence:
1. Turn off RF power.
2. Turn off power supply Vpd = +5V.
3. Turn off power supply Vcc = +28V.
Notes:
1. Vpd is used as a reference for the internal active bias circuitry. It can be used to turn on/off the amplifier.
