Description
M/A-COM’s MAATSS0001 is a 0.5 dB step GaAs
MMIC digital attenuator with 15.5 dB attenuation
range in a low cost QSOP-16 (SSOP-16) package.
It requires external DC blocking capacitors on the
RF ports, positive supply voltage and five individual
bit control voltages.
The MAATSS0001 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 MAATSS0001 is fabricated using M/A-COM’s
GaAs 1.0 micron process. The process features full
chip passivation for increased performance and
reliability.

QSOP-16 (SSOP-16)
Operating Instructions
The MAATSS0001 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 MAATSS0001 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 MAATSS0001 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.
For application information concerning this and
other M/A-COM products, please visit our website
at www.macom.com, where information including
soldering profiles, reliability procedures, and Sparameter data can be found.
