converting a portion of the substrate to a selectively etchable material in an area subjacent to the second area and extending only partially to the bottom surface of the substrate, selectively etching this etchable material to form a void, removing the mask layer to expose the isolation region...
For RF devices, the structural test also provides a good diagnostic resolution to the structural defects of RF circuits, especially for the high pin-count RF-SOCs. In this paper, the boundary-scan test is implemented on a 5-GHz RF pin using LC isolation networks to connect the RF lines ...

Nonreciprocal components, such as isolators and circulators, provide highly desirable functionalities for optical circuitry. This motivates the active investigation of mechanisms that break reciprocity, and pose alternatives to magneto-optic effects in o
=-12.5 dBm when RF=2.4 GHz and LO=2.25 GHz is demonstrated in this paper by using 0.18 μm deep n-well CMOS technology. The input return loss and output return loss are better than 15 dB for frequencies up to 6 GHz. On the other hand, a downconversion micromixer without deep n-well...
Due to the utilization of modified bias topology, resistive mixing core, and IF low-pass filter, this circuit has a very wide IF bandwidth. Moreover, the triple cascode structure is used in this mixer for high local oscillator (LO)-to-RF isolation and compact chip area. The measured ...
