Simplify Your Power Amplifier DPD Measurement Workflow
Application Notes
As modern mobile communications expand their capabilities and grow more complex, the associated growth in bandwidth, power consumption and linearity drive the need for new approaches for device characterization. Designers face challenges in generating accurate device models, minimizing design cycles, and certifying their RF device conformance.
Power amplifiers (PAs) are essential in modern RF communication chains. They convert a low-power signal to a higher-power one but are inherently non-linear. This non-linearity generates spectral regrowth that leads to adjacent channel interference and violation of the out-of-band emissions standards that regulatory bodies mandate. Non-linearity also causes in-band distortion, which degrades the bit error rate (BER) and data throughput of the communication system.
