GXSC 2GHz-18GHz Ultra-Wideband Downconversion SiP Empowers Electronic Countermeasures

Electronic countermeasures involve gaining dominance in the electromagnetic spectrum through precise sensing, rapid processing, and efficient control, thereby ensuring the normal operation of friendly equipment. With the rapid evolution of modern electronic technology, electromagnetic signals have become characterized by ultra-wideband, high-frequency, complex, and high-density characteristics. The operational spectrum now spans the ultra-wideband range of 2GHz to 18GHz, covering the operating frequencies of critical electronic equipment such as radar, communications, navigation, and guidance systems.

GXSC’s 2GHz–18GHz ultra-wideband downconverter SiP is designed for all-scenario signal acquisition, capable of comprehensively capturing various electromagnetic signals—including radar, communications, and navigation signals—within this frequency band. It eliminates the need for multiple modules, effectively preventing signal loss and switching delays, and meets the practical requirements of full-spectrum electronic warfare reconnaissance and jamming. This device utilizes SiP (System-in-Package) technology to integrate multiple discrete functional modules into a single package, reducing the volume by more than 60% compared to traditional discrete solutions and significantly reducing weight.

The device offers three selectable intermediate frequency (IF) bandwidths: 1 GHz, 400 MHz, and 50 MHz. The device features high channel linearity and offers strong anti-interference capabilities, high integration, compact size, and light weight when applied to broadband spectrum monitoring. It is suitable for broadband spectrum monitoring, electronic countermeasures, and other fields.
