Layout is important for proper 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 recommends the use of a high impedance printed inductor Lambda/4 in length.

The board was mounted to a baseplate 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 10C/W. The thermal resistance to the reference screw is 12C/W. 1. Use 1 or 2 ounce copper if possible. 2. Solder all eight leads of the CFK2162-P1 package to the appropriate electrical connection. 3. Solder the copper pad on the backside of the CFK2162-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 CFK2162-P1 package to provide a low thermal resistance path to the baseplate of the package. Ordering Information The CFK2162-P1 power stage is available in a SO-8 surface mount package. Devices are available in tape and reel. Ordering part numbers are listed.
