1. Circuit board material: Rogers RO4003.
PCB# SK40019-2. Material: Rogers RO4003.
The circuit board used in the final application should employ RF circuit design
techniques. RF signal lines should have 50
impedance. The package bottom
ground plane should be connected directly to PCB ground plane. A sufficient
number of via holes should be used to connect the top and bottom ground
planes. The evaluation circuit board shown is available upon request.
