Abstract

In this paper, a smaller and cheaper novel Subminiature Modular Plug-in Mini (SMPM) connector has been used to replace a K-type connector. The SMPM connector is installed on the top of printed circuit board (PCB) and soldering with an electrode to reduce the trace of a microstrip and to maintain the high frequency performance. Three designs of the PCB electrode have been simulated and verified experimentally. The optimized impedance mismatch of the soldering point between a SMPM connector and the PCB electrode is controlled within a range of ±2-Ohm. The 3-dB bandwidth of the whole setup including two SMPM connectors and a 2.5-cm long microstrip is above 25-GHz. This optimization can be used in designing high-speed PCB for the application of 100GBASE Ethernet.
