Customer Defined
The PCB dielectric between RF traces and RF ground layers
should be chosen to reduce RF discontinuities between 50
lines and package pins. M/A-COM recommends an FR-4
dielectric thickness of 0.008 (0.20 mm) yielding a 50
line
width of 0.015 (0.38 mm). The recommended RF metalization
is 1 ounce copper.
