Abstract :
This paper presents the design and experimental results of a monolithic cascode LNA for 28.5GHz applications using SiGe HBTs. It shows that designing circuits at frequencies beyond fT/3 is possible. The best experimental results are obtained at 26GHz with a 3.3V supply voltage: |S21| = 10.4dB, input and output matching better than -10dB. The measured noise figure is 6.4dB.
