60 Gbit/s time-division multiplexer in SiGe-bipolartechnology with special regard to mounting and measuring technique

Abstract
A 2:1 time-division multiplexer is presented which operates at up to 60 Gbit/s. This is the highest data rate ever achieved by an integrated circuit in any technology. The output voltage swing is 0.5 Vp-p (for 50 Ω on-chip matching and 50 Ω external load). The chips were fabricated using an advanced SiGe-bipolar technology (fT = 68 GHz) and then mounted on a comparatively simple measuring socket.
