Description
M/A-COM’s
MADCSM0011
integrated
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.
