used.
Handling Procedures
Please observe the following precautions to avoid
damage:
For IDD ~ 40 mA, R2 = 43 ohms;
IDD ~ 60 mA, R2 = 15 ohms;
IDD ~ 80 mA, R2 = 10 ohms.
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive to
electrostatic discharge (ESD) and can be damaged by
static electricity. Proper ESD control techniques
should be used when handling these devices.

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.
Designer’s Kit AM50-0003SMB
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.
