Circuit Board Material: 0.0147” Rogers Ultralam 2000, single layer, 1 oz
copper, εr = 2.45, Microstrip line details: width = .042”, spacing = .050”
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.
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 is recommended.
Evaluation Board Bias Procedure
Following bias procedure is recommended to ensure proper functionality of AP601 in a laboratory environment. The sequencing is not
required in the final system application.

Turn-on Sequence:
1. Attach input and output loads onto the evaluation board.
2. Turn on power supply Vcc = +12V.
3. Turn on power supply Vbias = +12V.
4. Turn on power supply Vpd = +5V.
5. Turn on RF power.
