Recommended PCB Configuration

Layout View

The AM50-0003SMB Designer’s Kit allows for immediate evaluation of M/A-COM’s AM50-0003. The Designer’s

Kit includes an evaluation board with mounted AM50-0003 and five loose AM50-0003’s. The evaluation board

consists of the recommended external surface mount circuitry, RF connectors, and a DC multi-pin connector, all

mounted to a multi-layer FR-4 PCB. The AM50-0003SMB evaluation PCB is illustrated below with all functional

ports labeled.

Customer Defined

The PCB dielectric between RF traces and RF ground layers

should be chosen to reduce RF discontinuities between 50 Ω

lines and package pins.

M/A-COM recommends an FR-4

dielectric thickness of 0.008” (0.20 mm) yielding a 50 Ω line

width of 0.015” (0.38 mm). The recommended RFmetalization

thickness is 1 ounce copper.
