N2 - In this paper, a 2.08 GHz Doherty rectifier using 0.25 μm Gallium nitride (GaN) HEMT process is presented with a dynamic input power distribution network (DIPD). The proposed rectifier consists of two rectifiers in parallel using 5x50 μm cells and 8x75 μm cells to have wide input dynamic range at the high input power level. Compact input matching networks for DIPD according to the input power is designed without an offset line. To verify the proposed method, a hybrid Doherty rectifier was designed and implemented. The measured results show the peak RF-to-dc power conversion efficiency (PCE) of 64.2-69.5% at the input power level of 32-38 dBm and the extended dynamic range (DR) with a PCE of better than 50% of 20 dB (from 21 to 41 dBm) with a dc load of 800 Ω.
