Description
M/A-COM’s MAAMSS0005 is a low current, high reverse
isolation LO buffer amplifier in a low cost SOT-143
plastic package. The MAAMSS0005 is ideally suited for
LO buffer handset applications in the Cellular, GPS and
PCS frequency bands.
The MAAMSS0005 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.
