Description
M/A-COM's MAAVSS0007 is a GaAs MESFET
MMIC voltage variable absorptive attenuator in a
lead-free SOIC-8 surface mount plastic package.
The MAAVSS0007 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.
1. Vcc = +5 VDC @ 50 µA maximum.
2. Vc = 0 VDC to +5 VDC @ 50 µA maximum.
3. External DC blocking capacitors are requirements on all RF
ports.
4. 39 pF used for data measurements.
The MAAVSS0007 is fabricated with a monolithic
GaAs MMIC using a mature 1-micron process. The
process features full chip passivation for increased
performance and reliability.
