The SpectrumSeries RFT-3200 downconverter and matching RFT-4200 upconverter are the industry’s first broadband frequency conversion products to allow the user to dynamically change the intermediate frequency (IF) on-the-fly. Designed to enable agile electronic warfare (EW) and electronic intelligence (ELINT) systems, these high-performance frequency converters offer customers the ability to dynamically respond to emerging electronic threats while also reducing upgrade costs through improved interoperability. Unlike existing frequency converters, these customizable converters allow the user to optimize the IF settings for the specific digitizer and mission needs, maximizing storage capacity and sensitivity. For example, for narrow signals of interest, the user can reduce the IF bandwidth to minimize the noise and improve the sensitivity, enabling the detection of low-amplitude signals that otherwise might be missed. The higher bandwidth settings are ideal for both efficiently scanning the electromagnetic spectrum for threats as well as processing wideband signals. This bandwidth optimization allows a single microwave converter to perform the same functions as multiple conventional frequency converters, thereby reducing system cost and size. Additionally, by adjusting the IF bandwidth, the converter can be easily paired with other digitizers, reducing total system cost by allowing the same converter to be used through multiple system upgrade cycles. In addition to a tunable IF, these converters feature RF performance up to 40 GHz, excellent phase noise characteristics, and phase coherent configurations. A modular design approach enables rapid customization to satisfy specific program needs as well as delivery in multiple form factors, including 19” rackmount, ruggedized half ATR chassis, and benchtop. The converters support a complete SCPI-based command set accessible over Ethernet or serial ports.
