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.
