Application Information
The MAAD-011021 is designed for extremely wide band and robust attenuation applications. It uses a
combination of series and shunt cold channel, multiple-gate FETs to achieve high linearity and accurate
attenuation repeatability. We recommend using double bonds at both RF input and output, as well as keeping
bondwires as short as possible. This part is the most accurate for X-band applications.
The MAAD-011021 has a built in inverter function which allows a single +5 V / 0 V single control for each bit.
This is useful if you require very fast switching times and have +5 V / 0 V available.
The MAAD-011021 is DC-coupled at both RF_IN and RF_OUT. If operation at DC is desired, 0 Ω jumpers (or
continuous 50 Ω RF lines) should be used in series with RF_IN and RF_OUT. Customer should take extra care to
ensure that the voltage at both RF_IN and RF_OUT are 0 V; excess voltage can damage the part. If operation at DC
is not required, simply use series blocking capacitors.
