Performance Graphs – Class AB Configuration (AP501-PCB)
The AP501-PCB and AP501 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 will have to
be mounted 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 heatsink 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:
a. Connect RF In and Out
b. Connect the voltages and ground pins as shown in the circuit.
c. Apply the RF signal
d. Power down with the reverse sequence
