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 VGG bias be applied prior to any VDD bias. Permanent damage may occur if this procedure is not followed. All FETs in the PA will draw excessive current and damage internal circuitry. All off-chip components are low-cost surface mount components obtainable from multiple sources. (0.020 in. x 0.040 in. or 0.030 in. x 0.050 in.)
