Operating Instructions
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.
