Amplifier linearization promotes efficiency in multi-carrier WCDMA basestation

Among the four building blocks of an AESA T/R module — power amplifier, low-noise amplifier, T/R switch, and beamformer IC — the beamformer is the one that most directly determines system-level radar performance.

GF’s comprehensive RF portfolio, including our industry-leading RFSOI, SiGe, 22FDX+ and RF GaN platforms, is purpose-built to push the boundaries of what’s possible in connectivity, but we’re not doing it alone. Together with innovative partners like Falcomm, we’re moving the industry forward, providing our customers with cutting-edge solutions to enhance performance, power and integration and create connected technologies with higher signal quality, better efficiency and longer battery life.

Integrated circuits are susceptible to electrostatic discharge (ESD) events. Real-time detection and alerting of ESD events in semiconductor manufacturing environments is the key to achieving well ESD control. Additionally, the magnitude and duration of an ESD event are strongly correlated with the specific type of ESD events.

This paper presents a comprehensive analysis of nonlinearities in differential pairs with source degeneration and their impact on wireline communication applications.
