A Load Insensitive Doherty Power Amplifier with better than −39dBc ACLR on 2:1 VSWR Circle using a Constant 50 Ω Trained Pre-distorted Signal

This paper presents a low-loss load-insensitive Doherty power amplifier (DPA) technique. The proposed DPA is insensitive to ohmic load variation by adjusting its supply voltages and input drive of the main and peaking stages in a mirrored approach. Moreover, a low-loss tunable matching network (TMN) is employed to cancel out any reactive part of...

A Package Integratable Six Port Reflectometer for RF Power Devices

Semiconductor power devices have a growing popularity in industrial, scientific and medical (ISM) band applications, such as microwave-heating, drying and plasma generation. A distinguishable property of these applications is the relentless pursuit of reliability, ruggedness, or the ability to withstand a mismatched loading condition without...
