Signal and Power Switches
Universal Digitally Controlled Analog Switches/Multiplexers

Jump to: Signal Switches Power Switches Specialized and Combined Devices

Our switches produce fast pulsed voltages with switching times as low as a few ns. They combine several digitally controlled electronic analog switches in a single device and are produced with a selectable number of switch channels, with the maximum number depending on the series. Each channel is a digitally controlled electronic analog switch for which the user can specify the switchable voltage.

The function of each channel corresponds to a conventional electromechanical relay, but the switching times are in the nanosecond range and the digital control inputs have a high input impedance. Similarly to an electromechanical relay, the control inputs are galvanically isolated from the signal lines.

Signal Switches (AMXT, AMXR)

Applications

  • Designed for driving small loads
  • Control of ion optics, e.g. entry or exit electrodes of ion traps, differential lenses, or BNGs (Bradbury-Nielsen gates)
  • Drivers of piezoelectric and electromagnetic valves or small motors

Properties

  • Maximum operating voltage (selectable for each channel separately): up to 1.5 kV (3 kV or more upon request)
  • Passive cooling for low output powers (several W)
  • Pulse bursts with high output frequencies possible

Signal Switches (Series AMXT)

  • Eurotainer design case
  • Up to 4 separate channels
  • Configuration only possible during production
  • Add-on options available for additional features
Modular switch AMXR with digital I/Os

Modular Switch System (Series AMXR)

  • 19" or 10" case
  • Up to 24 separate signal switch channels
  • Configuration can be modified by the user at any time
  • Additional modules available for specialized applications

Power Switches (19"-AMX, AMXR)

Our power switches differ from the signal switches by significantly higher switchable powers (i.e. higher output currents) and higher maximum output energies per pulse.

Applications

  • Designed for driving high capacitances at high frequencies
  • Supply of digital ion traps (DITs) or other multipoles (e.g. nanoparticle traps)
    • Optional high-voltage isolation allows for controlling traps operating at large bias potentials
    • Trilevel option allows for field-free phases and undisturbed injection, extraction, or manipulation of charged particles
  • Drivers for electromagnetic and piezoelectric valves and apertures
  • Motor drivers

Properties

  • Maximum operating voltage (selectable for each channel separately): up to 1.5 kV
  • Active (forced-air) cooling can dissipate high output powers (~ 100 W per channel)
  • Optional liquid cooling for quiet high-power operation (> 100 W per channel)
  • Continuously high output frequencies possible (typically 5 Mhz)
