A low noise amplifier (LNA) is proposed for a 35GHz ultra-wideband (UWB) system. The combination of a common-gate (CG) input stage and a common-source (CS) input cascode stage is exploited with a modified form of noise cancellation. The proposed LNA is implemented in a 0.18μm CMOS technology and achieves a power gain of 18dB, an average noise figure of 3.3dB, and better than -11dB of input/output...
This paper presents a fully integrated 60 GHz single stage power amplifier with cascode topology. The PA is designed on 0.25 mum SiGe:C BiCMOS technology. The technology provides ft and fmax ap 200 GHz. The PA has achieved the 1 dB gain bandwidth of more than 9 GHz from 57 GHz to 66 GHz and 3 dB gain bandwidth of more than 18 GHz (30 %) from 51 GHz to 69 GHz. The PA has been designed to have the wideband...
A high intercept points, cost-effective, and power-efficient switching FET double balanced mixer (DBM) is reported. The Switching FET DBM demonstrated in this work offers input intercept points (IIP3) and conversion loss typically 44 dBm and 8.5 dB respectively with 15 dBm LO power for the frequency band (RF: 900-2150 MHz, LO: 850-1950 MHz, IF: 50-200 MHz). The measured interport isolation is typically...
