The DF18141950B102T is an RF diplexer feature manufactured by Walsin, and is a SMD device that meets RoHS environmental compliance standards. It is used to combine two different frequencies in a single component, and its dual-band design makes it suitable for use as a 2-way signal splitter and/or combiner for RF communication signals. It features an insertion loss of 3.5 dB, which is low enough for it to be used in systems which require low noise levels. The component is used extensively in radio frequency transmission and reception applications, such as satellite TV, telephone, broadcasting systems, and cellular networks.
