Description
M/A-COM’s MAADSS0012 is a 1-bit, 21 dB step
attenuator. This GaAs MMIC digital attenuator is
packaged in an ultra small lead free 2 mm 8-Lead
PDFN surface mount package.
The MAADSS0012 digital attenuator will work with
any power source operating between 2.8 and 5.0
volts. This single bit attenuator is ideally suited for
use in wide band systems, up to 8.0 GHz where
good linearity and low insertion loss are required.
Typical applications for the MAADSS0012 attenuator
include WiMAX (802.16), Mesh Networks, Multi-
band repeaters and other linear systems.
3. Blocking capacitors are required on all RF ports.

is insignificant at the frequency
of use. At 800 MHz a capacitor value greater than 1000 pF is recommended.
