System Amplifier Handles Applications Up to 53 GHz
Addressing the urgent market demand for testing solutions in the Ka-, Q-, and V-bands, Rohde & Schwarz launched the R&S SAM200 system amplifier. An extension to the company's SAM100, which covers from 2 to 20 GHz, the new SAM200 and SAM200 Advanced models extend this capability from 20 to 53 GHz with up to 4 W of saturation power.
The SAM200 serves as a high-performance gain block, while the SAM200 Advanced introduces a smart, advanced feature set designed to streamline workflows.
The power amps include an integrated power detector, USB and LAN interfaces, and a web GUI. There's also a switchable three-path functionality that allows users to toggle between low noise/high gain, regular, and low gain modes to optimize error vector magnitude (EVM) signal quality.
Designed primarily for RF-component testing where signal generators or vector network analyzers may have limited output power, the SAM200 family's wide frequency coverage means that a single amplifier can now replace multiple narrowband units. They're available in both desktop and 4 HU rack-mounted configurations to suit various integration needs.
