Qorvo has unveiled SOI-based RF control products that simplify RF system design. This approach reduces circuit complexity in high-frequency systems through a design that eliminates negative power.


Qorvo announced on the 9th that it has unveiled a portfolio of Silicon-on-Insulator (SOI) based RF switches and Digital Step Attenuators (DSA). The product family is designed for the defense, aerospace, and infrastructure markets.

This portfolio is characterized by the application of a TTL-compatible control method, which eliminates the need for a negative power supply. Conventional RF control designs often required negative power supplies and complex bias circuits.

Qorvo explained that by simplifying this structure, it supports board design simplification, BOM (Bill of Materials) reduction, and signal routing improvement.

In addition, it was stated that it is designed to maintain RF performance requirements, such as high-speed switching, high isolation, and linearity, while reducing design complexity compared to existing GaAs-based RF control methods.

The product family consists of RF switches and digital attenuators, etc. The main products include SPDT switches (QPC2320, QPC2420), SP8T switches (QPC2180), and 6-bit digital attenuators (QPC5330, QPC5430).

These products support frequencies up to 30 GHz and can be applied to radar, satellite communications, electronic warfare (EW), test equipment, etc.

It is also designed to be controlled via digital interfaces such as SPI and I²C.

Qorvo stated that this portfolio provides a single platform instead of the existing method of combining components from multiple suppliers. They explained that this enables the standardization of RF control designs and increases reusability.

It is also reported that it will be utilized to improve design efficiency and integration in environments where broadband systems and signal integrity requirements are increasing.

The product is currently available for mass production, and Kobo announced that it plans to introduce the related technology at the IMS 2026 exhibition.
