V2 AM55-0004 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions is considering for development. Performance is based on target specifications, simulated results, and/or prototype measurements. Commitment to develop is not guaranteed. PRELIMINARY: Data Sheets contain information regarding a product M/A-COM Technology Solutions has under development. Performance is based on engineering tests. Specifications are typical. Mechanical outline has been fixed. Engineering samples and/or test data may be available. Commitment to produce in volume is not guaranteed. Recommended PCB Configuration 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 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.
