WiMAX Circulators Manage 0.20 dB Insertion Loss

July 13, 2007

WIMAX is on the rise with networks set to deploy in cities across the globe. To support this buildup, a family of single-junction surface-mount circulators is well suited for various WiMAX applications. The MAFR-000229000001, MAFR-000050-5S4C1T, MAFR-000159-5S4C1T, and MAFR000200-5S4C1T circulators split the WiMAX frequency bands. The family boasts typical performance of 0.20 dB insertion loss with 25 dB of isolation. Each part has intermodulation distortion (IMD) of –65 dBc. In addition, every circulator will provide peak power handling of 1000 W with continuous-wave (CW) forward and reverse power handling of 200 W. The MAFR-000229-000001 operates from 2.3 to 2.5 GHz while the MAFR-000050-5S4C1T operates from 2.5 to 2.7 GHz. The MAFR000200-5S4C1T spans 3.3 to 3.4 GHz. The last circulator in the family is the MAFR-000159-5S4C1T, which operates from 3.4 to 3.6 GHz. P&A: stock, $13.64 in quantities of 10,000.
