Description
M/A-COM’s MAAV-007941 is a GaAs MMIC voltage
variable absorptive attenuator in a low cost lead-free
SOIC 8-lead surface mount plastic package. The
MAAV-007941 is ideally suited for use where
attenuation fine tuning, fast switching and very low
power consumption are required.
Typical applications include radio, cellular, GPS
equipment and other automatic gain/level control
circuits.
The MAAV-007941 is fabricated with a monolithic
GaAs MMIC using a mature 1-micron process. The
process features full chip passivation for increased
performance and reliability.
