How Does Digital Pre-Distortion Achieve Closer Power Amplifier Saturation to for Better Linearity?
Getting maximum power from your SSPA without creating signal distortion is a constant challenge. This trade-off between power and linearity often forces unwanted compromises in system design and efficiency. The best way to optimize an SSPA is by using Digital Pre-Distortion (DPD).1 DPD digitally models the amplifier’s non-linear behavior, including memory effects2, and creates an […]
How to Accurately Determine RF Power Amplifier Drain Efficiency with Power Back-off?
You trust the datasheet for amplifier efficiency. But your real-world SSPA design overheats and performs poorly. I will show you how to measure the real efficiency and avoid these problems. To accurately determine RF power amplifier efficiency, you must go beyond the datasheet. Use a high-precision digital multimeter and a calibrated power meter. De-embed your […]
Why GaN SSPA Ruin Your High Linearity: Taming Trapping Effects via DPD and Power Back-off
Choosing between GaN and GaAs SSPAs is tricky. GaN’s smaller size is appealing, but its non-linearity can secretly tank your system performance1. Let’s find the right solution. Choose GaN for higher power density and a smaller footprint, but be prepared for its non-linearity. To maintain signal integrity, you must implement Digital Pre-Distortion (DPD) and a […]
