The new CX-4 is an ultra low noise FET preamplifier, operating in room temperature down to deep cryogenic environments (T = 4.2 K, liquid helium). It is an improved version of its predecessor NexGen3 KC05.
- ultra low input noise (typ. 0.31 nV/√Hz @ 1 MHz)
- frequency range 1 kHz to 4 MHz
- input impedance > 15 MΩ
- small size and tiny thermal load of only 300 μW per channel
- fully-automated plug’n’play room temperature controller included!
The development of CX-4 has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 721559.
