Qualcomm’s new RF Filter promises better 5G, WiFi on mobile devices

Chipmaker Qualcomm launched a new radio frequency filter designed for bands up to 7GHz today. The company calls this the Qualcomm ultraBAW RF filter technology and it is meant to optimize connectivity and power efficiency for 5G and WiFi devices, including smartphones, Internet of Things (IoT), automotive and industrial sensors. The company says ultraBAW will cover 2.7GHz to 7.2GHz bands. It is an extension of ultraSAW, which covers low-band frequencies between 600MHz and 2.7GHz.

Radio frequency filters are electronic components that isolate radio signals from the different spectrum bands which phones use in order to transmit and receive information. They also help eliminate noise or passthrough of unwanted signals. Christian Block, senior vice president and general manager, RF Front-End at Qualcomm, said the new filters are “crucial” to expanding 5G beyond mobile devices. He also said that the company is working with original equipment manufacturers (OEMs) to develop “next generation connected devices”.

Mobile devices have antennas that detect the signals available around the user at a time. RF Filters help separate the right bands, so devices can make use of the bands they need as required by the user. They also help separate 5G networks from WiFi networks, which helps reduce noise and enable faster downloads and uploads. The company said that devices with Qualcomm’s ultraBAW will get enhanced transmission rates and location services, among other benefits.

The company said ultraBAW is currently being sampled by its customers and it is expected to launch in the second half of 2022.
