Description
M/A-COM’s MAAV-008022 is a GaAs MMIC voltage
variable absorptive attenuator in a lead-free low-cost
SOIC 8-lead surface mount plastic package. The
MAAV-008022 is ideally suited for use where linear
attenuation fine tuning and very low power
consumption are required.

Typical applications include radio, cellular, GPS
equipment and automatic gain/level control circuits.
2. VCC = +3 VDC @ 50 µA maximum.
3. VC = 0 VDC to +3 VDC @ 50 µA maximum.
4. External DC blocking capacitors are required on all RF ports.
5. 39 pF used for data measurements.
The MAAV-008022 is fabricated with a monolithic
GaAs MMIC using a mature 1-micron process. The
process features full chip passivation for increased
performance and reliability.
