摘要:
MOCVD-grown InGaAs/InAlAs HEMTs with excellent noise performance comparable to that of MBE-grown devices have been successfully fabricated. A minimum noise figure lower than 0.30 dB has been obtained with an associated gain of approximately 15 dB at 12GHz. Furthermore, devices in ceramic packages have exhibited a minimum noise figure of 0.42 dB.
