Description
The CFK2062-P1 is a high-gain FET intended for driver 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 proper operation. Phase length of input and output 50Ω line varies
as a function of exact desired frequency of operation. Output
shunt inductor effects output performance. Celeritek recommends the use of a high impedance printed inductor
Lambda/4 in length.Please contact the factory for an evaluation board and/or more detailed application support.
