ABSTRACT
Coupled* striplines** are a very important network, employed in many devices like directional couplers, filters, and phase shifters. These devices in stripline configuration are bigger, but in general have better performances than the “cµ” counterpart studied in Chapter 5. Also at lower frequencies they can be used to transmit digital information at a high rate of speed, typically hundreds of MHz, where “ECL” devices are employed. In general, a high density PCB will contain striplines and µstrips as well.
