Low Noise Amplifiers 

 

The Caltech Microwave Research Group previously manufactured over 1000 amplifiers for other research centers. Revenue from these sales was used to support research at our lab.  The noise specified below is measured at 20K amplifier case temperature.  All future sales of cryogenic low noise amplifiers and antenna feeds are now handled through Steve Smith​, USA 424-456-7722, Steve@CosmicMicroTech.com, www.CosmicMicrowaveTechnology.com.
