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.
3. Blocking capacitors are required on all RF ports.
4. RF Port and Ground pin capacitors are 1000 pF.
