Description
The D50AA30Z4A is a high performance Alumina (Al
2
O
3
) Surface mount
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 terminating circulators, and for use in power
monitoring. The attenuator is also RoHS compliant!
