DESCRIPTION
Agilent Technologies’s The output is internally matched to 50Ω. The input is optimally internally matched for lowest noise figure into 50Ω. The input may be additionally externally matched for low VSWR through the addition of a single series inductor. When set into the bypass mode, both input and output are internally matched to 50Ω. Simplified Schematic The MGA-725M4 offers an integrated solution of LNA with adjustable IIP3. The IIP3 can be fixed to a desired current level for the receiver’s linearity requirements. The LNA has a bypass switch function, which sets the current to zero and provides low insertion loss.
