AP622

UMTS-band 4W HBT Amplifier Module

Performance Graphs

W-CDMA 3GPP Test Model 1+64 DPCH, 60% clipping, PAR = 8.6 dB @ 0.01% Probability, 3.84 MHz BW, Vcc = +28V, Icq = 120 mA

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
