Description:
The XQF1306 is a low profile, miniature
quadrifiliar feed network in an easy to use surface
mount package designed for XM and Sirius Satellite
radio receivers. The XQF1306 is designed to
combine the signals from a helix antenna into one
coherent output and is an ideal solution for any
satellite radio receiver where electrical
performance, reliability and ease of use is
preferred. Parts have been run through rigorous
qualification testing and units are 100% tested.
They are manufactured using materials with x and y
thermal expansion coefficients compatible with
common substrates such as FR4, G-10 and
polyamide.
