Chuang, "60-GHz unbalanced-fed bandpass-filtering on-chip Yagi antenna in GIPD
technology," in Proceedings of the 10th European Conference on Antennas and Propagation, EuCAP 2016, Davos, Switzerland, April 2016.
The design theorem of this filter, proposed in  in GIPD
process, has the central frequency 2.9 GHz and  in PCB process, has the central frequency 5.2 GHz, has yielded very good performance using just a small area, which is appropriate for SiP technology.
QEWC has signed the Water Purchase Agreement for 36 million imperial gallons per day (GIPD
), which is the output of the new plant.
