Model XC0450E-20S Rev E 20 dB Directional Coupler Description The XC0450E-20S is a low profile, high performance 20dB directional coupler in a new easy to use, manufacturing friendly surface mount package. The XC0450E-20S 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 100 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. Produced with 6 of 6 RoHS compliant tin immersion.
