EDA Software Design Flow Considerations For The RF/Microwave Module Designer


Miniaturization of consumer products, aerospace and defense systems, medical devices, and LED arrays has spawned the development of a technology known as the multi-chip module (MCM), which combines multiple integrated circuits (ICs), semiconductor die, and other discrete components within a unifying substrate for use as a single component. This white paper outlines the steps for implementing an... » read more

RF/Microwave EDA Software Design Flow Considerations For PA MMIC Design


In this white paper, a gallium arsenide (GaAs) pseudomorphic high-electron mobility transistor (pHEMT) power amplifier (PA) design approach is examined from a systems perspective. It highlights the design flow and its essential features for most PA design projects by illustrating a simple Class A GaAs pHEMT monolithic microwave IC (MMIC) PA design using Cadence AWR Microwave Office circuit desi... » read more

Load-Pull Analysis For Optimizing PA Performance


In load pull calculations, power amplifiers are going to need harmonic load pull analysis and load pull contours with wideband electromagnetic tuners. Working with RFIC power amplifiers is difficult for the myriad of concurrent design elements that they affect, transmission line voltage, signal interference, and impedance to name a few. In load pull calculations, power amplifiers are going t... » read more

CMOS And SOI Invade RF Front End


By Mark LaPedus The next-generation 4G wireless standard known as long-term evolution (LTE) presents some new and difficult design choices for OEMs. One of the more difficult choices involves the less glamorous, but arguably the most critical part in a handset—the radio-frequency (RF) front-end. Typically, the RF front-end often comes in a module and includes various key components, such ... » read more
