3. Exceeding any one or combination of these limits may cause
permanent damage to this device.
4. M/A-COM does not recommend sustained operation near
these survivability limits.
Operating Instructions
The MAATSS0017 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 MAATSS0017 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 MAATSS0017 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.

other M/A-COM products, please visit our website

soldering profiles, reliability procedures, and Sparameter data can be found.
