RF Match Data shown in the performance graphs was taken in the test circuits shown at right and on page 3. 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. Please contact the factory for an evaluation board and/or more detailed application support.

Thermal Considerations
Product Specifications - July 1997
(4 of 4)
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 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-P3 package to the appropriate electrical connection. 3. Solder the copper pad on the backside of the CFK2162-P3 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-P3 package to provide a low thermal resistance path to the baseplate of the package.
