Murata Launches Ultra‑Compact SAW Devices to Meet 5G Demands

Murata today unveiled a new line of surface acoustic wave (SAW) devices engineered for RF filtering and duplexing. These components tackle the escalating demand for miniaturization in mobile phones and other wireless gadgets, including smartphones, Wi‑Fi routers, M2M modules, and IoT devices that rely on LTE and Wi‑Fi.

Modern smartphones combine multiple high‑performance features—advanced cameras, larger batteries, and expansive displays—which consume valuable internal space. To free room for additional components and maintain performance, designers increasingly rely on smaller RF substrates to manage wireless signals efficiently.

Simultaneously, smartphones now operate across multiple frequency bands and leverage advanced LTE features—carrier aggregation, MIMO—that complicate RF design. As 5G rolls out, these complexities will accelerate, demanding even more sophisticated RF circuitry.

Consequently, compact RF components—particularly SAW filters and duplexers—are essential. SAW devices sit between antennas and transceivers, isolating specific frequency bands. Today’s smartphones, even mid‑range models, incorporate 14–15 SAW devices, while global flagship devices can contain 30–40 units. The clear need for smaller, high‑performance SAW solutions has driven Murata to deliver a new product family that meets this requirement.

Leveraging its extensive in‑house expertise, Murata engineered these miniature devices to handle low‑frequency bands—ranging from 800 MHz to 2.6 GHz—without compromising performance. The resulting components match or surpass competitors in key metrics while occupying a fraction of the space.

Engineers seeking compact, high‑performance SAW solutions for 5G and beyond now have a reliable option from Murata.
