An enhancement mode PHEMT MMIC with integrated dual low noise amplifiers, dual switches, and dual distortion compensation power amplifiers is presented. It is used in an 802.11abgn FEM (front end module) which further integrates the antenna diplexer, LNA post filters, PA pre-filters, and baluns. The LNAs provide less than 1.2 dB noise figure in the 2.4/5-6 GHz receive chains at 16 dB gain and 10 mA...
A complete antenna-to-CMOS FEM (front end module) is described. Its simple assembly belies the high integration level of diplexer, switches, LNAs, linear PAs, load insensitive power detection, baluns, post and pre filtering. The active components are based on enhancement mode PHEMT while filtering and 4 times 6 mm substrate are in plastic encapsulated LTCC. The FEMS covers 802.11 abgn 2.4 GHz and...
