Abstract :
We report a new integrated circuit for multiplexing and demultiplexing at rates of 100 Gb/s. In transistor multiplexer/demultiplexer circuits, the operating data rate is limited by transistor bandwidth. The demonstrated circuit, which uses terahertz Schottky diodes, readily attains the necessary bandwidths. The IC, based in the diode nonlinear-transmission line (NLTL) technology, consists of an array of four sample-hold gates driven by NLTL strobe generators. To permit use in multiplexing, the sample-hold gates use a six-diode configuration with 150 GHz output bandwidth. Initial measurements with simple data patterns at 104 Gb/s are demonstrated
