D30NA20Z4

Model D30NA20Z4
Surface Mount Attenuator
30 Watts, 20dB
The D30NA20Z4 is a high performance Aluminum Nitride (AlN) chip
attenuator intended as a cost competitive alternative to Beryllium Oxide
(BeO). The attenuator is well suited to all cellular frequency bands such as;
AMPS, GSM, DCS, PCS, PHS and UMTS. The high power handling makes
the part ideal for inter-stage matching, directional couplers, and for use in
isolators. The attenuator is also RoHS compliant!
