en.Wedoany.com Reported - Nuvotronics, the RF and millimeter-wave component brand under U.S.-based Cubic Defense, officially released the PSB1030148 four-channel switch filter bank on April 23, 2026, in Durham, North Carolina, covering the 17.5 to 40 GHz frequency band. This product is designed for broadband filtering requirements in advanced RF and electronic warfare systems, integrating four independent passbands into a single compact package with a 1 GHz overlap between adjacent bands for seamless frequency coverage. The product is currently available for order.
Scott Meller, Vice President and General Manager of Nuvotronics, stated in an official release: "Nuvotronics continues to push the boundaries of RF performance while reducing the size and weight of mission-critical systems. The new 18 to 40 GHz switch filter bank achieves high isolation and fast switching in a compact form factor, enabling software-defined radios to maintain system link budgets and operate effectively in crowded and contested RF environments."
Regarding core RF specifications, the four channels of the PSB1030148 cover 17.5 to 24 GHz, 23 to 29.5 GHz, 28.5 to 35 GHz, and 34 to 40 GHz respectively. Single-channel insertion loss is kept within 7.5 dB, and stopband rejection can reach 75 dB, helping to attenuate spurious interference and maintain signal clarity during critical missions. Each channel can also handle hot-switching input power up to 24 dBm without interrupting system operation. The device package measures only 15.8 by 16.3 by 4 millimeters, features a bottom surface-mount interface, and supports standard reflow soldering and epoxy attachment processes.
In terms of band switching speed, the PSB1030148 demonstrates a key performance metric: switching speed is less than 200 nanoseconds. This characteristic allows the product to perform dynamic frequency hopping without triggering power-down sequences, directly improving link continuity in scenarios requiring millisecond-level real-time response, such as electronic warfare.
Tom Dekker, Senior Product Manager at Nuvotronics, further highlighted the breakthrough significance of this filter bank in terms of size and weight: "Software-defined radios increasingly require filtering capabilities that are compact, precisely engineered, and easily integrated into complex RF architectures. Compared to traditional cavity filter and suspended substrate filter technologies, Nuvotronics' switch filter bank reduces size and weight by a factor of six while maintaining high performance. The compact form factor and surface-mount interface simplify high-density circuit board assembly integration, helping engineers reduce system complexity without sacrificing capability."
From an application deployment perspective, the target scenarios for the PSB1030148 span multiple fields including electronic warfare, satellite communications, and test and measurement. Nuvotronics also offers customized multi-channel switch filter bank solutions extending from 2 GHz to 60 GHz to meet the needs of a broader range of agile multi-band RF systems. The company's proprietary PolyStrata® micromachining technology is the core process enabling the high integration and low loss achieved in this product. The product has already been deployed in aerospace, defense, satellite communications, and other sectors, with manufacturing executed under AS9100D aerospace quality management system certification.
