U9397A/C FET Solid State Switches (SPDT)

Flyers

Key Features

  • Prevent damage to sensitive components with low video leakage < 10 mVpp
  • Minimize crosstalk with exceptionally high isolation 100 dB @ 8 GHz
  • Maintain fast throughput with industry leading settling time for FET switches of 350 μs
  • Eliminate the need for external drivers with an integrated TTL/CMOS driver

Description

Keysight Technologies, Inc. U9397A and U9397C FET solid state switches, SPDT provide superior performance in terms of video leakage, isolation, settling time, and insertion loss across a broad operating frequency range. The U9397A/C are particularly suitable for measuring sensitive devices and components, such as mixers and amplifiers, where video leakage may cause damage or reliability issues. High isolation minimizes crosstalk between measurements, ensuring accurate testing and improving yields. A switching speed of 500 ns makes these ideal for high-speed RF and microwave SPDT switching applications in instrumentation, communications, radar, and many other test systems.

The U9397A/C incorporate a patented design which reduces the settling time to < 350 μs (measured to 0.01 dB of the final value). Other FET switches available today have a typical settling time of > 50 ms.

The U9397A/C switches have a GaAs FET MMIC at each RF port, and the integrated TTL/CMOS driver is configured in such a way that when either the RF1 or RF2 port is not selected to RFCOM, the port is terminated to 50 Ohm.

Specifications

Specifications refer to the performance standards or limits against which the solid state switches are tested.

Typical characteristics are included for additional information only and they are not specifications. These are denoted as "typical," "nominal" or “approximate" and are printed in italic.
