Description
M/A-COM’s AM50-0004 is a high dynamic range,
GaAs MMIC, low noise amplifier in a low cost, SOIC
8-lead, surface mount, plastic package. It employs
external input matching to obtain optimum noise
figure performance and operating frequency
flexibility. The AM50-0004 also features flexible
biasing to control the current consumption vs.
dynamic range trade-off.
The AM50-0004 can
Pin Configuration
operate from any positive supply voltage in the 3 V
to 8 V range. Its current can be controlled over a
range of 20 mA to 60 mA with an external resistor.

The AM50-0004 is fabricated using a low-cost 0.5-
micron gate length GaAs process. The process
features full passivation for increased performance
and reliability. The AM50-0004 is 100% RF tested
to ensure performance specification compliance.

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 .008” (0.20
mm) yielding a 50 Ω line width of 0.015” (0.38 mm). The recommended
RF metalization is 1 ounce copper.
Designer’s Kit AM50-0004SMB
The AM50-0004SMB Designer’s Kit allows for immediate evaluation of M/A-COM’s AM50-0004. The Designer’s
Kit includes an AM50-0004 mounted on an evaluation board and five loose AM50-0004’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 AM50-0004SMB evaluation PCB is illustrated below with all functional
ports labeled.

The DC connector on the Designer’s Kit PCB allows convenient
DC line access. This is accomplished by the one or more of the
following methods.
1. A mating female multi-pin connector (Newark Electronics
Stock # 46F-4658, not included).
2. Wires soldered to the necessary pins (not included).
3. Clip leads (not included).
