CHIP MODULE STRUCTURE AND METHOD AND SYSTEM FOR CHIP MODULE DESIGN USING CHIP-PACKAGE CO-OPTIMIZATION
A chip module, including a radio frequency integrated circuit (RFIC) chip and a package, and a method and system for designing the module. Chip and package design are performed so the RF front end (FE) is split between chip and package. The chip includes an amplifier with a first differential port and the package includes a passive device and matching network with a second differential port connected to the first differential port. The second differential port is power matched to the first differential port using complex power matching based on port voltage reflection coefficients in order to achieve improved performance (i.e., a peak power transfer across a bandwidth as opposed to at only one frequency). The power matching process can result in a chip power requirement reduction that allows for device size scaling. Thus, designing the chip and designing the package is iteratively repeated in a chip-package co-optimization process.
