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
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 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 PDC,
DCS-1800, DCS-1900 and other PCN/PCS base
stations. It is also useful as a gain block, buffer,
driver, and IF amplifier in both fixed or portable PDC
and PCN/PCS systems.
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.
