Keysight Technologies Inc. USB Preamplifier, 2 to 50 GHz, Cable-less
The Keysight U7228F is a USB preamplifier designed for use from 2 GHz to 50 GHz, offering high gain and low noise figure performance in a compact, cable-less form factor. It is part of the U7220 Series of USB preamplifiers and is engineered to enhance signal sensitivity for a variety of high-frequency measurement applications, including spectrum analysis and signal detection. The U7228F connects directly to compatible Keysight X-Series signal analyzers via USB, eliminating the need for external power supplies or interconnecting cables. This integration simplifies setup and reduces measurement uncertainty by minimizing signal loss and mismatch. The preamplifier is powered and controlled through the USB interface, and its performance is fully characterized and traceable to international standards. The U7228F is suitable for demanding R&D, manufacturing, and field environments where precise, repeatable measurements are required.
