Description
The MAADSS0014 is a 4-Bit, 2dB step GaAs MMIC
digital attenuator in a lead-free 3mm PQFN-16LD
surface mount plastic package. The MAADSS0014
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.
3. Blocking capacitors are required on all RF ports.
4. RF Port and Ground pin capacitors are 1000 pF.
