Description
M/A-COM’s MAADSS0010 is a 1 dB step GaAs
MMIC digital attenuator with 31 dB attenuation
range in a lead-free QSOP-16 (SSOP-16) package.
It requires external DC blocking capacitors on the
RF ports, positive supply voltage and five individual
bit control voltages.

Operating Instructions
The MAADSS0010 is designed to operate with 5 V logic levels.
The difference between +3 V and +5 V operation is minimal for
small signal performance. IIP3, however, is a strong function of
voltage. +3 V is the minimum voltage at which the product will
reliably operate.

The MAADSS0010 requires a parallel interface that allows the
user to enter a 5 bit digital word. Each state increments the
attenuation by 1.0 dB giving a total range of 31 dB.
2 dB
4 dB
The MAADSS0010 is not internally DC blocked. This means
that the device requires DC blocking capacitors on the RF1 and
RF2 ports. M/A-COM recommends 0.1 uF to allow for the entire
8 dB
16 dB
frequency range to be utilized.
applications can use smaller value capacitors as DC blocks.
