Johanson has made all efforts to ensure data that reflects the actual performance of the parts. Changes to substrate, mounting and matching will affect component performance. Customers must validate performance in their system.
All Numbers are typical values with the following measurement conditions:
- Series mounting
- Horizontal orientation
- Infinite heatsink
- Duty cycle = 100%
- Ambient temperature and maximum temperature: as shown in the ‘RF parameters’ window
- Pad dimensions and spacing as recommended on our website https://www.johansontechnology.com/pcb-pad-layout-recommendations
