Selecting the Right Low-Loss Materials for High-Frequency Circuits

As communication systems move to higher frequencies (e.g. 5G/6G) and data transfers move to higher rates, minimizing transmission losses and maintaining signal integrity become very important. This is where low-loss materials come in. With several different options for low-loss materials available in the market, this article looks at the key properties and factors to consider that guide the selection of materials for high frequency applications.

Low-Loss Materials: The Key Enablers for High-Speed Connectivity

Transmission losses become increasingly significant as communication systems move toward higher frequencies, making low-loss materials essential to preserve signal strength and integrity. These materials are critical for technologies such as 5G mmWave and future 6G telecommunications which is expected to see deployment around 2030, as well as for automotive radar systems for advanced driver assistance systems (ADAS). Similarly, data center infrastructure is shifting toward ultra-high data rates exceeding 200Gbps amplifying the need for materials that can perform reliably and maintain signal integrity under such demanding conditions.

AGC

AGC's multi-material division develops low-loss dielectric substrates for high-frequency applications, such as high-speed digital and wireless communications (e.g. 5G, mmWave automotive radar), aerospace, and satellite communications.

Resonac

Resonac is a Japanese materials manufacturer that offers materials solutions for several markets including mobility (Li-ion battery materials, automotive products), chemical (olefins, graphite, basic chemicals), and others (polymers, ceramics, coatings, etc.), with a focus on semiconductor and electronic materials. It provides low-loss thermoset resins for high frequency applications including 5G, automotive radar, and high-speed digital.

Panasonic

Panasonic Industry manufactures multi-layer circuit board materials which includes low-loss laminates for printed circuit boards (PCBs) for high frequency applications such as high-speed digital (HSD) and 5G.
