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.

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

frequency

range

to

be

utilized.

Higher

frequency

applications can use smaller value capacitors as DC blocks.
