Rev. A
Hybrid Couplers
3 dB, 90
Description
The 1X703 is a low profile, miniature 3dB hybrid coupler in an easy to use
surface mount package designed for the 3.3 to 3.7 GHz bandwidth. The
1X703 is designed for balanced amplifiers and signal distribution and is an
ideal solution for the ever increasing demands of the wireless industry for
smaller printed circuit boards. Parts have been subjected to 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.
