Description
M/A-COM’s AM50-0006 is a high dynamic range, GaAs MMIC,
low noise amplifier in a low cost, SOT-26 miniature 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 include receiver front ends in PDC1500, DCS-1800, DCS-1900, PHS and other PCN/PCS applications.
It is also useful as a gain block, buffer, driver and IF amplifier in both
fixed and 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 reliability. The AM50-0006 is 100% RF
tested to ensure performance specification compliance.

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
is 1 ounce copper.
