The XC1900A-03S is a low-profile, high-performance 3dB hybrid coupler that features a new, user-friendly and manufacturing-friendly surface-mount package. It is designed for NMT band applications. The XC1900A-03S is specifically tailored for balancing power and low-noise amplifiers, along with signal distribution and other applications that require low insertion loss and strict amplitude and phase balance. It can be used in high-power applications up to 45 watts. 

It has a thermal expansion coefficient of 435, the same as that of the polyimide substrate (such as the strictly tested FR0-435). It offers two models: 5/6 tin-lead (XC0450A-03P) and 6/6 RoHS-compliant soldering (XC0450A-03S).
