Description

The MAADSS0016 is a 5-Bit, 1dB step GaAs MMIC

digital attenuator in a lead-free 3mm 16 lead PQFN

surface mount plastic package. This device 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.

The MAADSS0016 is part of a digital attenuator

family. This family includes 4, 5, and 6 bit

attenuators with 0.5, 1, or 2 dB steps and up to 31.5

range.

3. Blocking capacitors are required on all RF ports.

4. RF Port and Ground pin capacitors are 1000 pF.
