Performance Graphs – Class B Configuration
The AP501 can be adjusted to operate at lower current biasing levels by modifying the R7 resistor for improved efficiency
performance. The configuration shown on this page has the AP501 operating with Icq = 250 mA (Icc = 400 mA @ 27 dBm).
Output L-C matching components have been added externally on the circuit to optimize the amplifier for ACPR performance at
this biasing configuration.
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
