Description
M/A-COM’s AM50-0006 is a high dynamic range,
GaAs MMIC, low noise amplifier in a
SOT-26 surface mount plastic package.
It employs external input matching to obtain
optimum noise figure performance and operating
frequency flexibility.
The AM50-0006 also features flexible biasing to
control the current consumption vs. dynamic range
trade-off. The AM50-0006 can operate from any
positive supply voltage in the 3 V to 8 V range. Its
current can be controlled over a range of 3 mA to 20
mA with an external resistor.
The AM50-0006 is ideally suited for use where low
noise figure, high gain, high dynamic range, and low
power consumption are required.
Typical
applications included receiver front ends in PDC1500, DCS-1800, DCS-1900 and other PCN/PCS
applications. It is also useful as a gain block, buffer,
driver, and IF amplifier in both fixed or portable PDC,
PHS, and PCN/PCS systems.
The AM50-0006 is fabricated using a low-cost
0.5-micron gate length GaAs process. The process
features full passivation for increased performance
and reliability. The AM50-0006 is 100% RF tested
to
ensure
performance
specification
compliance.

Handling Procedures
†
Meets JEDEC moisture sensitivity level 1 requirements.
Please observe the following precautions to avoid
damage:
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.

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 RF metalization thickness
is 1 ounce copper.
