Abstract :
This paper presents a practical evaluation method for package and PCB effects on RFICs in W-CDMA applications. The package and PCB interconnects are characterized rigorously by establishing their equivalent parasitic circuits with the help of the 3-D EM-simulation tool. For demonstration, two 1.9 GHz RFICs were fabricated by a GaAs HBT foundry process, and then housed in the leadless wirebond packages, and finally surface-mounted onto PCBs for testing. With the established equivalent parasite circuits, the package and PCB effects can be included in the RFIC simulation in the design stage. The simulated results agree quite well with the final measured results.
