Abstract:
This paper presents a reconfigurable Doherty-to-balanced (D2B) power amplifier (PA) operating in the Ka band for 5G applications. The circuit, designed in a 0.13μm GaAs HEMT technology, uses a single-pole-double-throw (SPDT) switch that can enable the reconfiguration between a 50W and a short. The PA achieves a peak power added efficiency (PAEsat) of 21.7% at a saturated output power (Psat) of 28.5dBm in the Doherty mode and 31.4% PAEsat with 29.6dBm Psat in balanced mode. The balanced PA offers good immunity to load mismatches up to a 3:1 VSWR achieving output power fluctuation within 3 dB.
