Description
M/A-COMs 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 PDC-
1500, 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.

Customer Defined
The PCB dielectric between RF traces and RF ground layers
should be chosen to reduce RF discontinuities between 50
lines and package pins. M/A-COM recommends an FR-4
dielectric thickness of 0.008 (0.20 mm) yielding a 50Ωline
width of 0.015 (0.38 mm). The recommended RF metalization
is 1 ounce copper.
