Abstract
The present invention allows for the use of chip-package co-design of RF transceivers and their components by using discrete active devices in conjunction with passive components. Two particular components are described, including voltage controlled oscillators (VCOs) and low noise amplifiers (LNAs). The high quality passive components for use in the VCOs and LNAs may be obtained by the use of embedded passives in organic substrates. Further, the embedded passives may have multi-band characteristics, thereby allowing multi-band VCOs and LNAs to be implemented with fewer components. In situations where size is a concern, the active devices and passive components utilized in an RF transceiver may be implemented in a low form factor module of less than 1.1 mm thick according to an embodiment of the invention.
