A Sub 1 W Load-pull Quarter-wave Prematching Network Based on a Two-tier TRL Calibration Transistors used for cellular and PCS infrastructure applications are required to amplify signals with a peak-to-average ratio that can exceed 13 dB, resulting in a peak envelope power (PEP) approaching 1 kW. This PEP requirement...
