This paper presents a fully integrated 60 GHz two stage power amplifier using cascode topology. The design procedure and measurement results are presented. The PA is implemented in a 0.25 μm SiGe:C BiCMOS technology featuring ft and fmax ~ 200 GHz. The saturated output power of the amplifier has been improved with the help of current combining and matching techniques. At 60 GHz the power amplifier...
A folded double-balanced mixer has been implemented in a 0.18 mum BiCMOS technology for wireless local positioning applications. Operating in the unlicensed ISM band centred at 5.8 GHz with a 150 MHz bandwidth and with a very low IF frequency band from 500 kHz up to 5 MHz, the mixer achieves 17 dB voltage conversion gain, 8.5 dB noise figure and input IP3 of - 6 dBm. The mixer power consumption is...
This work presents an active downconverter targeted for integration in 60 GHz high speed data communication RF front-ends. The designed downconverter has been realized in 0.25 mum SiGe BiCMOS technology with ft around 200 GHz. The downconverter consists of a single balanced mixer with an on-chip balun for differential to single ended conversion. High linearity and bandwidth are the main design goals...
