We have many years of experience in the development of cryogenic electronic components and modules, which are used at low to lowest temperatures (77K...4,2K). Custom specific units like

amplifiers, coupling stages, filters etc. can be tailored to your needs. Additionally, we can offer a variety of already developed standard modules.

Highly sensitive FT-ICR amplifier module for use at 4K

Pictures: Low-noise amplifier module for the frequency range DC...4MHz, suited for continuous operation at 4K (= - 269°C) (left). Highly sensitive FT-ICR amplifier module for use at 4K. This module provides two independant channels for narrow band (Δf = 1kHz) and wideband (40MHz) FT-ICR detection of single or few ions (right).
It's e.g. in use at the University of Mainz, Department of Physics
in the

g-factor calcium experiment.

Cryogenic Low Pass Filter Unit KA-Fil 2a

Our filter unit KA-Fil 2a contains 5 independent low pass filters for room temperature and cryogenic use. The main application is the creation of low noise environments in cryogenic experimental setups. Internal Schottky diodes, which are able to operate in cryogenic environments, allow for deliberate filter bypassing, in order to apply electrical pulses or frequency bursts.
