Product Overview

The 34905A CAL DU from Keysight Technologies is a 2GHz, dual, 50 ohm, 1:4 RF multiplexer module for 34970A/34972A data acquisition/switch units. The Keysight 34905A RF multiplexer module for the 34970A/34972A data acquisition/switch units offers broadband switching capabilities for high frequency and pulsed signals. Use it to route test signals between device under test and signal generator, oscilloscope, spectrum analyzer or other instrumentation. The RF multiplexer is arranged as two independent 1 x 4 multiplexers, each with a common shield and a switched centre conductor. Connections can be made directly to SMB inputs with 2GHz usable bandwidth or to the BNC to SMB adapters provided with 1GHz bandwidth. Multiple banks may be cascaded together for applications requiring even larger topologies, create a stubless 16:1 multiplexer in a single frame.
  • Calibrated with data and uncertainties RF multiplexer module
  • Dual 4 channel RF multiplexer, 60ch/sec speed
  • Uses SMB connectors
  • Cascade together for up to 16:1 multiplexer
  • Common low (unterminated) type
  • 42V maximum voltage, 0.7A maximum current, 2GHz bandwidth, 60/s open/closed speed
  • Less than 6µV thermal offset, 20W power rating
  • 1GHz bandwidth through BNC to SMB adapter cable
  • Less than 0.5ohm initial closed channel, greater than 1Gohm isolation (ch to ch, ch to earth)
  • Operating temperature range from 0°C to 55°C


34905A dual 4-channel RF multiplexer module, Certificate of calibration, 10 cables (50 ohm (SMB to BNC)).
