Abstract :
The stability of InP HEMTs preamplifiers has been investigated in time and frequency domains at various cryogenic temperatures. It achieved a gain fluctuation of 5×10-6/√ Hz and an Allan time of 9 seconds at 4 GHz bandwidth. The stability of a sideband separating (2SB) mixer receiver is tested with the IF (4-8 GHz) preamplifier at 4 K.
