Description
M/A-COM’s MAATSS0016 is a 4-bit, 2-dB step GaAs
MMIC digital attenuator in a lead-free TSSOP-16
surface mount plastic package. The MAATSS0016 is
ideally suited for use where high accuracy, very low
power consumption and low intermodulation products
are required. Typical applications include radio, cellular,
wireless LANs, GPS equipment and other gain/level
control circuits.

4. Blocking capacitors are required on all RF ports (39 pF
used for data measurements).
5. Vs = +5 ± 0.2 VDC must be applied at RF1 or RF2 using a
10 Kohm or greater pull-up resistor.
The MAATSS0016 is fabricated using a mature 1
micron GaAs MESFET process. The process features
full chip passivation for increased performance and
reliability.
