WEMA19: AI-Based Digital Predistortion in MATLAB
RF engineers need to squeeze the last dB of performance from their transceiver front ends. For signals like OFDM with a high PAPR, that often means using techniques like digital predistortio...
WEMA20: External Optimization and AI/ML Training of a 3GHz Filter Using Python in ADS
A 3GHz filter is created and optimized in a headless, automated method in Keysight ADS. With today's complex systems of EDA environments, foundry PDKs and tech files, and simulators, an...
WEMA21: 200W Ka-Band High Power Amplifier Technology Realized by an 8-Way Power Combiner with 30W GaN-Based Chips.
This presentation will discuss a highly-efficient and highly-reliable power amplifier using a bare-die direct-mounting technology and an 8-way power combiner. The most important technology to design a...
WEMA22: mmWave CMOS Power Amplifier Design and Simulation with Custom Compiler and PrimeSim
CMOS technologies support FET devices with Ft and Fmax well beyond 400GHz, which make it possible to design RFICs operating in 5G mmWave and automotive Radar frequency bands. We�...

WEMA25: Advancements in Linear and Non-Linear Bidirectional Impedance and Stability Analysis
While bidirectional impedance probes have existed in microwave CAD software for some time, they have historically not accounted for the presence of feedback. In the most recent release of Cadence AWR ...
WEMA26: Advances In Thermal Analysis and Over-The-Air Electromagnetic Analysis of Advanced Microwave Devices and Front-End-Modules
Performance requirements for microwave devices are leading to shrinking geometries, complex structures, and new materials. Additional to increasing power densities, devices are being deploye...
WEMA27: High-Performance RF AFE with Integrated DPD/CFR
Digital pre-distortion (DPD) is a signal processing technique that compensates for nonlinear distortions in radio-frequency (RF) power amplifiers (PAs). RF PAs increase the power output in wireless ba...
