Tiny SAW devices target 5G applications
New surface acoustic wave (SAW) devices from Murata nfor RF filtering and duplexer applications address the ongoing and ever increasing need to reduce the size of components in mobile phones, especially with the coming of 5G.

To address these advancements in smartphone technologies, smaller RF circuit components are required. This is particularly true in the case of SAW devices which are placed between antennas and transmitting/receiving circuits to extract wireless signals at certain frequencies. They are components with a higher demand for smaller size because smartphones, even mid range models for specific regions, feature 14 to 15 SAW devices, while premium-class models that can be used worldwide have as many as 30 to 40 SAW devices. Demonstrably, there’s clearly a need for a space-saving solution to the size of SAW devices, one that Murata has addressed and achieved with this new range of devices.

Using its in-house experience and technology, Murata has successfully designed the devices to be smaller-sized products that support low frequencies despite the technical challenges in doing so. One of the chief benefits of this to the designer being that the tiny devices handle frequency bands from 800 MHz to 2.6 GHz. So in their smaller sizes, the devices equal or have better performance characteristics than similar products from the competition. Murata will gradually add new models to the range to support the LTE communications standard worldwide.
