This article presents and discusses the design of RF circuits using Integrated Passive Devices (IPDs) technology appropriate for the development of low-cost and high performance System-in-Package (SiP) wireless transceivers. Two examples, a 6-GHz voltage-controlled oscillator (VCO) and a 60-GHz 90° coupler are introduced to demonstrate the implementation of RF circuit design using an IPD process. Experimental results of the VCO and the 90° coupler will be presented and compared with the simulation results.
