Description
M/A-COM’s MAADSS0008 is a 1-bit, 15-dB step
GaAs MMIC digital attenuator in a lead-free SOT-25,
5 lead surface mount plastic package. The
MAADSS0008 is ideally suited for use where high
accuracy, very low power consumption and low
intermodulation products are required.
Typical applications include wireless handsets, base
stations, wireless LAN equipment, GPS receivers
and any RF applications with automatic gain/level
control circuits.
The MAADSS0008 is fabricated as a monolithic
GaAs integrated circuit using a mature PHEMT
process. The process features full chip passivation
for performance and reliability.
