Description
M/A-COM’s MADCSM0012 integrated
downconverter combines a low noise amplifier, a RF
amplifier, a downconverting mixer, an IF amplifier,
and LO buffer amplifier. The MADCSM0012 is
packaged in a low cost 3mm 16-Lead PQFN with an
exposed pad for improved high frequency
grounding.
M/A-COM designed the MADCSM0012 for handsets
requiring wide dynamic range and low power
consumption. By application of a suitable control
voltage to pin 6, the linearity of the device can be
controlled in real time to keep the current as low as
possible
The MADCSM0012 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.
