Hybrid Couplers
3 dB, 90
Description
The JX503 is a low profile, miniature 3dB hybrid coupler in an easy to use
surface mount package designed for W-CDMA, UMTS and other 3G
applications. The JX503 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.
