Page 12: Product Overview
Introduction Product Overview The Keysight U9400A/C consists of 8/18 GHz solid state FET transfer switches which are developed based on GaAs FET Monolithic Microwave Integrated Circuit (MMIC). These solid state switches provide high isolation; low video leakage; superior insertion loss and return loss across a broad operating frequency range. -
Page 13: Features
– Prevent damage to sensitive devices or components with low video leakage of typically 90 mVpp – Maintain fast throughput with industry leading settling time for FET switches of 350 μs – Eliminate the need for external drivers with integrated TTL–compatible driver Keysight U9400A/C Operating and Service Manual... -
Page 14: Circuit Logic
Introduction Circuit Logic The Keysight U9400A/C switches come with an integrated TTL-compatible driver that is configured in such a way that when a TTL high (logic 1) is applied to the CTRL pin of the switch, the paths from Port 1 to Port 2 and Port 3 to Port 4 of the switch are at high isolation, while the paths from Port 1 to Port 3 and Port 2 to Port 4 are at low loss. - Page 15 Introduction RF Port 1 RF Port 2 TTL driver CTRL circuits RF Port 3 RF Port 4 Figure 1-3 Diagram of U9400A/C switches in State B Keysight U9400A/C Operating and Service Manual...
