Short range wireless technology


Dialog Semiconductor’s short range wireless ICs deliver significant efficiency enhancements and enable devices, ranging from DECT phones to wireless headsets to game console controllers, to benefit from improved battery life.

Our mass-produced solutions for worldwide DECT and 2.4 GHz radio frequency bands have broken barriers and brought the benefits of CMOS to RF applications.Reliable, powerful yet easy-to-use, our products deliver outstanding performance and flexibility. So you can create systems that really stand out from the crowd.

Dialog works closely with industry bodies to define and implement new wireless standards and technologies. As a result, our solutions for real-time wireless voice and data applications ensure the earliest support for the improved and innovative features specified in these new releases.

Our portfolio covers all regional versions of the DECT plus the 2.4 GHz DCT protocol. And, we are at the forefront of technology developments to bring the benefits of wireless networking to new markets. For example, as co-developers of the DECT ultra-low-energy operating mode, we're opening the door to all kinds of novel smart home, healthcare and machine-to-machine applications.
