Description
M/A-COM’s AM50-0003 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 AM50-0003 also
features flexible biasing to control the current
consumption vs. dynamic range trade-off. The
AM50-0003 can operate from any supply voltage in
the 3V to 8V range.
Its current can be
controlled over a range of 20 mA to 80 mA with an
external resistor.
The AM50-0003 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 AMPS,
GSM, and ETACS base stations. It is also useful as
a gain block, buffer, driver, and IF amplifier in both
fixed and portable cellular and 900 MHz ISM
systems.
The AM50-0003 is fabricated using a low-cost 0.5-
micron gate length GaAs process. The process
features full passivation for increased performance
reliability. The AM50-0003 is 100% RF tested to
ensure performance specification compliance.
