Description
VC3
M/A-COM’s MAATSS0022 is a 0.5 dB step GaAs
MMIC digital attenuator with 15.5 dB attenuation
range in a lead-free MSOP-10 package. It requires
external DC blocking capacitors on the RF ports,
positive supply voltage and five individual bit control
voltages.
The MAATSS0022 is particularly suited where high
attenuation accuracy, low insertion loss and low
intermodulation products are required.
Typical
applications include base stations, wireless data,
and wireless local loop gain level control circuits.

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.
4. 0 = 0.0 V ± 0.2 V, 1 = Vs = 5.0 V ± 0.2 V.
