In this paper a new design of MMIC based LNA is outlined. This design uses adiscrete 100-nm InP HEMT placed in front of an existing InP MMIC LNA to lowerthe overall noise temperature of the LNA. This new approach known as theTransistor in front of MMIC (T+MMIC) LNA, possesses a gain in excess of 40dBand an average noise temperature of 9.4K compared to 14.5K for the equivalentMMIC-only LNA measured across a 27-33GHz bandwidth at a physical temperature of8K. A simple ADS model offering further insights into the operation of the LNAis also presented and a potential radio astronomy application is discussed
