The C20A50Z4 is high performance Alumina (Al2O3) surface mount
termination intended as a cost competitive alternative to Aluminum
Nitride (AlN). The termination 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 high power 90
degree couplers and for use in microstrip circuits. The termination is also
RoHS compliant!
