Description
M/A-COM's MADCSM0001 is a downconverter suitable
for Dual-Band and Triple-Mode Operation. The
MADCSM0001 has a 50-ohm matched input, consumes
low DC power and incorporates an on-chip switch that
determines CDMA and AMPS mode select. The designer
can tailor the linearity and gain performance of the
MADCSM0001 according to the system needs.

The MADCSM0001 is ideally suited for wireless
applications where low noise, low current and high
linearity are important features.

The MADCSM0001 is fabricated using M/A-COM's
0.5-micron low noise E/D GaAs MESFET process. The
process features full passivation for increased performance
and reliability.
