A miniaturized and low-insertion-loss V-band bandpass filter implemented on the integrated passive device (IPD) is demonstrated. The architecture is composed of two quarter-wavelength transmission lines with vias, which form the two spiral-type resonators. Then, aperture compensation technique is applied to enhance the coupling between two resonators. The filter exhibits low insertion loss around...
A novel system on package (SoP) RF frontend module for X-band frequency modulated continuous wave (FMCW) sensor is presented in this paper for short distance moving object detection. A multifunction RFIC chip realized by typical 1P6M 0.18 ??m deep n-well CMOS technology, a multilayer 180?? hybrid and two embedded ring filters, two sets of antenna arrays, and all other necessary components are all...
