The 1420 MHz emission from hydrogen, arising from its hyperfine transition, is crucial in radio astronomy for mapping galaxies and studying the interstellar medium due to hydrogen's abundance. Detecting these weak signals requires a low noise floor and low noise temperature in the receiving systems. Low noise amplifiers (LNAs), especially those using GaAs FETs, are designed to minimize their own noise while effectively amplifying the faint hydrogen signals. Thus, effective noise management is es
