Abstract :
A 20 GHz channel emulator for broadband differential data links has been developed using a trace overlaid with lossy materials and a two stage programmable Finite Impulse Response (FIR) filter. It allows to emulate the main channel and the cross-talk in the data links. The hardware design and emulation procedure are described. The emulated channel matches the target channel, validating the design methodology.
