XC1900A-20SR Anaren

Model XC1900A-20 Rev E 20 dB Directional Coupler Description The XC1900A-20 is a low profile, high performance 20dB directional coupler in a new easy to use, manufacturing friendly surface mount package. It is designed for DCS and PCS band applications. The XC1900A-20 is designed particularly for power and frequency detection, as well as for VSWR monitoring, where tightly controlled coupling and low insertion loss is required. It can be used in high power applications up to 150 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-20P) and 6 of 6 tin immersion (XC1900A-20S) RoHS compliant finishes.
