Description
The CFK2162-P5 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
+34 dBm. The device is easily matched and provides excellent
linearity at 2 Watts. 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.
