The XC1900A-05 is a low profile, high performance 5dB directional coupler in a new easy to use, manufacturing friendly surface mount package. It is designed for DCS and PCS applications. The XC1900A-05 is designed particularly for non-binary split and combine in high power amplifiers, e.g. used along with a 3dB to get a 3-way, plus other signal distribution applications where low insertion loss is required. It can be used in high power applications up to 200 Watts. Parts have been subjected to rigorous qualification testing and they are manufactured using materials with coefficients of thermal expansion (CTE) compatible with common substrates such as FR4, G-10, RF-35, RO4350, and polyimide. Available in both 5 of 6 tin lead (XC1900A-05P) and 6 of 6 tin immersion (XC1900A-05S) RoHS compliant finishes.
