Description

M/A-COM’s

MADCSM0011

integra t e d

downconverter combines a downconverting mixer,

an IF amplifier, a LO buffer amplifier and an output

mode switch. The MADCSM0011 is packaged in a

low cost 3mm 12-Lead PQFN package with an

exposed

pad

for

improved

high

frequency

grounding.

M/A-COM designed the MADCSM0011 for handsets

requiring wide dynamic range and low power

consumption.

A mode switch is incorporated into

the MADCSM0011 to switch between CDMA and

AMPs operation.

The MADCSM0011 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.
