Now you have me reading RF filters for dummies. Here's the intro
The proliferation of 4G LTE networks and the ubiquitous nature of Wi-Fi are driving a dramatic increase in the number of radio frequency (RF) bands that smartphones and other mobile devices must support. These bands need to be isolated within each device using filters to avoid interference and dropped calls. This is becoming more difficult as governments throughout the world increasingly allocate limited spectrum next to existing bands, often with minimal or nonexistent guard bands. As a result, filter selection has become a key consideration for designers of next-generation smartphones and mobile devices. This book explains the various filtering technologies that are available to address different filtering challenges and how these solutions have evolved to become key enablers of the global LTE transition.
Okay so they (AKTS) are the first on the 5G wave?
The top 10 competitors in Akoustis' competitive set are Richardson RFPD, Newlans, Resonant, Pasternack, Mfreq, KS Electronics, Avnet, Point Nine Technologies, Terasys Technologies and Digi-Key. Together they have raised over 77.5M between their estimated 20.0K employees.
