The MAATSS0022 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 MAATSS0022 requires a parallel interface that allows the

user to enter a 5 bit digital word. Each state increments the

attenuation by 0.5 dB giving a total range of 15.5 dB.

The MAATSS0022 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.
