Abstract :
We experimentally investigate the isolation effect of the noise coupling in X/Ku-band transceiver SiP fabricated on low-temperature co-fired-ceramic (LTCC) multilayer substrate, using a double-stacked electromagnetic bandgap (DS-EBG) structure. The fabricated transceiver SiP is composed of Ku- band transmitter and X/Ku-band receiver. To prevent the simultaneous switching noise coupling from digital circuits, a DS-EBG structure was designed and implemented to the transceiver SiP. The effect of DS-EBG, which gives 30 dB stopband over X/Ku-band ranges, was demonstrated through frequency and time domain measurement.
