Abstract
This paper describes the design and realization of a wide band single balanced fully integrated up-conversion mixer. The mixer has a RF bandwidth from 1 to 11GHz and an IF at 14 GHz, with an 1GHz bandwidth. This requires a LO frequency range from 15 to 25GHz. This single balanced mixer needs a single RF signal and a differential LO signals. The wide LO band prevents the use of a passive single to differential converter. We choose to integrate an active single to differential converter on chip. The output of the mixer core needs to be buffered. This to prevent unwanted mixing due to reflected signals from the IF output. To have enough buffering two single amplifiers are included.
