This paper discusses how multiuser massive microwave and mm-wave MIMO can support communications among many users over a given allocation of spectrum, along with manageable array form factors and power consumption. ABSTRACT | Large arrays of radios have been exploited for beamforming and null steering in both radar and communication applications, but cost(More)
Class C power amplifiers offer higher efficiency than class B power amplifiers, but suffer from poor linearity. A feedback based biasing system to improve the linearity of a class C power amplifier is designed. A class B amplifier with a gain of 20 dB and 20 MHz bandwidth at 900 MHz acts as the launching point for the design. The biasing and output network(More)
