The Better DC Blocks!

DC Blocks provide AC coupling of high-speed serial data streams in modern communication systems. The key metrics are insertion loss, bandwidth, flatness over the band, working voltage and return loss. Because the frequencies range from 16 kHz to 110 GHz, measuring the characteristics of the DC blocks is a challenge. Amotech provides evaluation boards to correlate customer measurements with Amotech’s. Accurate 3D HFSS models are available for circuit simulation.
