Abstract :
In this paper the results on a study of using a low cost SiGe:C BiCMOS technology dedicated to few GHz applications up to 30GHz are discussed. Spiral inductors with SRF higher than 30GHz are not available at the foundry library. Accordingly, inductors wit a SRF higher than 45GHz and a Q of 5 at 30GHz were obtained. The design, implementation and test of a broad band feedback resistive amplifier are also presented. It has a 3dB bandwidth from 12 to 32GHz and ldB bandwidth of 11GHz, a maximum gain of lOdB and return losses better then lOdB.
