| Tóm tắt≠ | Load-Pull is an experimental technique for characterizing and optimizing RF power amplifier performance under varying load and source impedance conditions. Introduced by Davidson et al. in 1990, load-pull measurements vary the load impedance seen by the amplifier while recording output power, efficiency, and linearity. Load-pull reveals contours of constant gain, efficiency, and stability, enabling optimal impedance matching for maximum performance. Essential for power amplifier design and characterization. | The Method of Moments (MoM) is a powerful numerical technique for solving electromagnetic boundary integral equations derived from Maxwell equations. Pioneered by Roger Harrington in 1968, MoM discretizes only radiating surfaces and boundaries (antennas, conductors, dielectrics), not the surrounding space, making it efficient for radiation and scattering problems. MoM remains the standard tool for antenna design, electromagnetic compatibility analysis, and RF/microwave engineering. |
