Description: The HMC1126ACEZ is a gallium arsenide (GaAs), pseudomorphic high electron mobility transfer (pHEMT), low noise amplifier that operates from 400 MHz to 52 GHz. The HMC1126ACEZ provides 12 ...

But to make that measurement you need an amplifier circuit designed for the thermocouple being used. Linear Technology LTC 1049 Low Power Zero-Drift Operational Amplifier with Internal Capacitors ...
