Surface Mount Attenuator
The D30NA30Z4 is a hig h performance Aluminum Nitride (AlN) chip
attenuator intended as a cost co mpetitive alternative to Beryllium O x ide
(BeO). The attenuator is well suited to all cellular freq uency bands such as;
AMPS, GSM, DCS, PCS, PHS and UMTS. The high power handling makes
the part ideal for inter-stage matching, directional cou plers, and for use in
isolators. The attenuator is also RoHS compliant!
