Anaren Microwave announced the introduction of its surface mount, Xinger®-brand quadrifilar helix feed network ("quadfeed") component for satellite radio receivers. Developed in cooperation with engineers at Washington D.C.-based XM Satellite Radio Holdings Inc., the miniature 2.320-2.345 GHz quadfeed part number XQF1306 combines four signals from a quadrifilar helix antenna into one coherent output signal for amplification to the radio receiver. The new Xinger quadfeed is designed to be compatible with both the XM and the Sirius Satellite Radio networks, as the two companies have agreed to operate on a single standard in next generation systems.
Frequency is 2.32 - 2.345 GHz, and insertion loss is 0.35 dB max. /0.30 dB typical. Return Loss is 15 dB min./ 20 dB typ., while amplitude balance is ± 0.25 dB max./ ± 0.10 dB typ. Phase balance is ± 5 degrees max. (± 2 degrees typ.).
