Evaluation Board Layout
RF Layer is 0.008” thick Rogers Corp.
RO4003C, r = 3.38. Metal layers are 0.5
oz. copper. The microstrip line at the
connector interface is optimized for the
Southwest Microwave end launch connector
1092-01A-5.
The pad pattern shown has been developed
and tested for optimized assembly at
TriQuint Semiconductor. The PCB land
pattern
has
been
developed
to
accommodate lead and package tolerances.
Since surface mount processes vary from
company to company, careful process
development is recommended.
