            Abstract : 
A low noise solid state amplifier for replacement of a Ka-band TWTA is described. Eight stages of amplification, which utilize cathode notch InP Gunn diodes, provide a gain of 37 /spl plusmn/ 3 dB with an associated N. F. ranging from 13.3 to 16.3 dB in the 27-39.5 GHz band.
