Model C18A50Z4
Surface Mount Termination
18 Watts, 50
Ω
Description
The C18A50Z4 is a high performance RoHS compliant Alumina (Al2O3)
surface mount termination intended as a lower cost alternative to
Aluminum Nitride (AIN) and Beryllium Oxide (BeO). The SMD 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 90º hybrids, directional couplers, and for use in isolators.
