Signal and Power Switches

Universal Digitally Controlled Analog Switches/Multiplexers

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 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)

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)

Power Switches (Series 19"-AMX)

19" case Up to 4 separate channels Configuration only possible during production Add-on options available for additional features

Modular Switch System (Series AMXR)

19" or 10" case Up to 12 separate power switch channels Configuration can be modified by the user at any time Additional modules available for specialized applications
