GXSC‘s 2GHz-18GHz Ultra-Wideband Downconversion SiP is widely used in broadband spectrum monitoring

Broadband spectrum monitoring primarily provides long-term or real-time monitoring of spectrum usage, identifies interference, unauthorized signals, or spectrum occupation patterns, with the goal of ensuring spectrum compliance, maintaining order in the electromagnetic environment, and supporting spectrum planning and interference management. Its technical focus lies in high-precision measurement and analysis (such as signal parameter estimation, modulation identification, and interference source localization). This application solution utilizes GXSC’s ultra-wideband down-conversion SiP, which is currently widely deployed.

This GXSC device is a 2 GHz–18 GHz broadband downconversion SiP that downconverts the 2–18 GHz broadband spectrum to 1.8 GHz. Users can choose from three intermediate frequency (IF) bandwidth options: 1 GHz, 400 MHz, and 50 MHz. The device features high channel linearity and, when applied to broadband spectrum monitoring, offers advantages such as strong anti-interference capability, high integration, compact size, and light weight. It is suitable for applications in broadband spectrum monitoring, electronic countermeasures, and other fields.
