Keysight U9428B/001/101 Solid State FET Switch

Overview

The Keysight U9428B/001/101 is a solid state FET switch for broadband RF applications with extended frequency coverage to 50 GHz. This SP8T configuration provides excellent isolation and minimal video leakage, making it particularly suited for measuring sensitive RF components across a wider frequency range. With isolation reaching 100 dB at 9 GHz and 70 dB at higher frequencies, plus video leakage below 270 mVpp, the switch maintains measurement accuracy while protecting delicate circuits from high-level RF signals.
