This article presents an integrated radio frequency (RF) front end for the use in frequency bands up to 10GHz. It consists of an actively matched low noise amplifier (LNA) and a single multi-tanh Gilbert cell mixer. Its applications include frequency-modulated continuous wave (FMCW) radar front ends or single down conversion communication systems. The circuit is completely inductor-less. Using a negative resistance bandwidth enhancement technique, a 1dB bandwidth of 11.2 GHz is reached. The input reflection coefficient is below -7 dB up to a frequency of 7GHz within a printed circuit board (PCB) test bed. The single-sideband (SSB) noise figure amounts to 7dB and the small-signal gain is 26dB. The complete circuit is implemented using an IBM 180 nm SiGe BiCMOS process, occupies an active area of only 0.078 mm 2 and consumes 57mW of DC power.
