Class AB Configuration (AP513-PCB)
The AP513-PCB and AP513 module is configured for Class AB by default. The resistor – R7 – which sets the current draw for
the amplifier is set at 0
in this configuration. Increasing that value will decrease the quiescent and operating current of the
amplifier module, as described on the next page.

Notes:
1.
Please note that for reliable operation, the evaluation board and
mounting plate will have to be attached to a much larger heat sink
during operation and in laboratory environments to dissipate the
power consumed by the device.
The use of a convection fan is also
recommended in laboratory environments. Details of the mounting holes
used in the WJ mounting plate are given on the last page of this datasheet.
2.
The area around the module underneath the PCB should not contain any
soldermask in order to maintain good RF grounding.
3.
For proper and safe operation in the laboratory, the power-on sequencing
should be followed:
1.
Connect RF In and Out
2.
Connect the voltages and ground pins as shown in the circuit.
3.
Apply the RF signal
4.
Power down with the reverse sequence
