In addition to their range of standard products, Astute can provide technical support to develop customer-specific solutions in conjunction with the manufacturer.

“Linear Systems designs and builds extremely low noise JFETs and components that provide a unique performance in high-end signal chain solutions. This partnership will greatly benefit those engineers globally searching for components needing discrete based solutions. 

Their products are particularly popular with Defence customers; the ultra-low-noise JFETs enable designers to build more sensitivity and capability into their sensor systems, which translates directly into greater functionality.

Important to our Hi-Rel customers, Linear Systems works hard to safeguard the long-term availability of their products, which is especially important for keeping defence and military systems in service.”
