Murata has announced Radisol, an innovative product designed to suppress interference between nearby antennas with low insertion loss, improving isolation and antenna radiation efficiency. This world-first solution is specifically engineered to meet the demands of compact modern devices like smartphones and wearables, offering benefits such as reduced power consumption, miniaturized construction and enhanced communication quality.
Radisol has been adopted by Motorola Mobility in the new Edge series of smartphones scheduled to be released in August 2024. Motorola has realised a method of improving the characteristics of Wi-Fi antennas by using Radisol.
Each Radisol component operates as a dedicated filter circuit designed specifically to mitigate the antenna interference associated with a specific communication band. The compact component integrates one capacitor and two inductors, providing band- stop filter characteristics within a single chip. Radisol features a unique design that utilizes the generation of lossless mutual inductance by two magnetically coupled coils.
