Qualcomm’s new ultraBAW RF Filter tech promises to improve your phone’s 5G and Wi-Fi 6E performance

Back in early 2020, Qualcomm had announced its ultraSAW filter technology alongside the launch of the Snapdragon X60 modem. Today, the company is expanding on the available RF Filters with the announcement of the Qualcomm ultraBAW RF filter technology for bands up to 7GHz.
Radio Frequency (RF) Filters are a fascinating piece of technology, something that we don’t actively think about but one that is crucial for the smooth functioning of our digital lives. As the name would imply, an RF Filter filters out the noise and reduces interference from external signals, ensuring that only the needed frequencies are transmitted in the best possible way. Within the context of phones and phone-adjacent mobile equipments, an RF Filter will isolate radio signals from the different spectrum bands that phones use to receive and transmit information.
