Abstract :
A miniature and broadband, K-band p-HEMT LNA MMIC, that incorporates simple lumped matching elements and series bias topologies, has been developed for LMDS (Local Multi-point Distribution Service) and satellite communication. The gain and noise figure is 14.5+/-1.5 dB and 1.7+/-0.2 dB, respectively, at frequencies between 23 and 30 GHz. The die size of the MMIC is 0.9 mm/sup 2/, the gain-density of this MMIC is as high as 14.4 dB/mm/sup 2/, which is more than two times larger than that of previously reported.
