Recommended PCB Configuration

Cross Section View

Rev. V4

The PCB dielectric between RF traces and RF

ground layers should be chosen to reduce RF

discontinues between 50 Ω lines and package pins.

M/A-COM recommends an FR-4 dielectric

thickness of 0.008” (0.2 mm) yielding a 50 Ω line

width of 0.015” (0.38 mm). The recommended

metallization thickness is 1 ounce copper.

The AM55-0016SMB Designer’s Kit allows for

immediate evaluation of M/A-COM’s AM55-0016.

The Designer’s Kit includes an AM55-0016, an

evaluation board and a floppy disk containing

typical performance data and a DXF file of the

recommended PCB layout. 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 AM55-0016SMB evaluation PCB is illustrated

below with all functional ports labeled.
