Hybrid Couplers
3 dB, 90°
Description
The 1X603 is a low profile, miniature 3dB hybrid coupler in an easy to use
surface mount package for ISM and wireless LAN applications. The 1X603
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.
