TLine
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 in. (0.2 mm), yielding a
50-
line width of 0.015 in. (0.38 mm). The recommended
metalization thickness is 1 oz. copper.
Shaded traces are vias to DC routing layer and traces on DC
routing layer.
Biasing Procedure
The AM55-0004 requires that V
bias be applied prior to
any
V
DD
bias. Permanent damage may occur if this
procedure is not followed. All FETs in the PA will draw
excessive current and damage internal circuitry.
