We fabricated low-jitter 2:1 multiplexer (MUX) and 1:2 demultiplexer (DEMUX) modules for bit error rate testers that can be used for research into ultra-high-bitrate communication subsystems and devices with bitrates of over 100 Gbit/s. The 1:2 DEMUX IC design took into consideration an IC layout allowing module pin placement for optimal utility. With regard to mounting, the 2:1 MUX and 1:2 DEMUX modules were constructed using transmission lines of grounded coplanar waveguide (G-CPW) configuration, which offers excellent high-frequency characteristics. These modules operated at 113 Gbit/s with a low root mean square jitter of 548 fs and 587 fs, respectively.
