A 0.8–11GHz 0.15μm pHEMT reconfigurable low power consumption distributed low noise amplifier for wireless home networks

A design methodology of reconfigurable distributed low noise amplifier (RDLNA) dedicated for wireless home communications operating from 0.8GHz to 11GHz is presented in this paper. This RDLNA is suitable to operate in two different operation modes: low power consumption mode and high performance mode. The used technology is 0.15μm InGaAs Active Layer pHEMT Process provided by TRIQUINT. The circuit is composed of six unit gain cells. Each cell is mounted in cascode topology. The design and the simulation results are detailed and commented. In low power consumption mode, the RDLNA has a gain of 14.0±0.3dB a noise figure (NF) of 2.4dB on average and a power consumption of 15.4mW (1.0V). In high performance mode, it demonstrates a gain of 19.8 ± 0.2dB, a NF of 1.7dB on average and a power consumption of 94.0mW(2.0V).
