Xinger® III 90 Degree Hybrid Couplers Anaren Xinger® III 90 Degree Hybrid Couplers are low profile, high performance couplers in easy-to-use surface-mount packages. These couplers are designed specifically for balanced power and low noise amplifiers, plus signal distribution and other applications where low insertion loss and tight amplitude and phase balance is required. Xinger III 90 Degree Hybrid Couplers offer the same high performance as previous Xinger generations - plus lower insertion loss (down to 0.12dB), higher isolation, increased power-handling ability, better phase/amplitude balance, and superior CTE characteristics compared to ceramics. RoHS compliant and 100% RF-tested, Anaren Xinger III 90 Degree Hybrid Couplers can be used in high power applications and are ideal for AMPS, DCS, PCS, GSM, WCDMA, WIMAX, 3G, 4G, and LTE band applications.
