Abstract
In embodiments, a radio frequency (RF) module includes an RF switching device, an RF active device, a passive device and a control device formed on a high resistivity substrate. The passive device can include a shallow trench device isolation region having a plate shape and formed at a surface portion of the high resistivity substrate, deep trench device isolation regions extending downward from a lower surface of the shallow trench device isolation region so as to define at least one isolated region therebetween, at least one insulating layer formed on the high resistivity substrate, and at least one passive component formed on the insulating layer.
