Description
The CFK2062-P1 is a high-gain FET intended for dri-
ver amplifier applications in high-power systems, and output
stage usage in medium power applications at power levels up to
+30 dBm. The device is easily matched and provides excellent
linearity at 1 Watt. Manufactured in Celeritek's proprietary
power FET process, this device is assembled in an industry
standard surface mount SO-8 power package that is compatible
with high volume, automated board assembly techniques.

RF Match Data shown in the performance graphs was taken
in the test circuit shown at right. Layout is important for prop-
er operation. Phase length of input and output 50
line varies
as a function of exact desired frequency of operation. Output
shunt inductor effects output performance. Celeritek recom-
mends the use of a high impedance printed inductor
Lambda/4 in length.Please contact the factory for an evalua-
tion board and/or more detailed application support.

Thermal Considerations
The data shown was taken on a 31 mil thick FR-4 board with 1 ounce copper on both sides. The board was mounted to a base-
plate with 3 screws as shown. The screws bring the top side copper temperature to the same value as the baseplate. The thermal
resistance to the indicated reference lead,
JL, is 12C/W. The thermal resistance to the reference screw is 14C/W.
1. Use 1 or 2 ounce copper if possible.
2. Solder all eight leads of the CFK2062-P1 package to the appropriate electrical connection.
3. Solder the copper pad on the backside of the CFK2062-P1 package to the ground plane.
4. Use a large ground pad area with many plated through-holes as shown.
5. If possible, use at least one screw no more than 0.2 inches from the CFK2062-P1 package to provide a low thermal resistance
path to the baseplate of the package.
