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 perform-

ance. IIP3, however, is a strong function of volt-

age. +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.

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 fre-

quency range to be utilized. Higher frequency

applications can use smaller value capacitors as

DC blocks.
