FEM simulation in Keysight ADS

In this video Rob Smith describes how to use the FEM simulator in Keysight ADS to simulate microwave package transitions and wire bonds. The key to success is to co-design the IC and the package, in order to optimise the performance of the packaged device rather than the IC on its own.

Doherty Power Amplifiers Move to mmWave

Doherty PAs are widely used below 6 GHz to improve power-added efficiency (PAE) for communications applications. Although the benefits of the Doherty architecture are compelling, the challenges of designing Doherty PAs increase as the frequency of operation moves toward mmWave. This article in the September issue of Microwave Journal describes the design of a Doherty PA MMIC for the 5G frequency band at 28 GHz, fabricated on the commercial 0.15 µm G28v5 GaN on SiC foundry process from Wolfspeed and assembled into a cost-effective, compact 4 mm x 4 mm QFN package.
