Description
The MAAD-008866 is a 6-bit, 0.5-dB step GaAs
digital attenuator in a lead-free 4mm PQFN-24LD
surface mount plastic package. The MAAD-008866
is ideally suited for use where high accuracy, very
low power consumption and low intermodulation
products are required. This part can be used in all
75 ꢀ systems operating up to 1 GHz.
5. Blocking capacitors are required on all RF ports
