This paper presents a theoretical analysis of the load modulation conditions in a Load Modulated Balanced Amplifier architecture as a function of the type of hybrid coupler employed. In particular, two cases are examined: the 90-degree hybrid coupler and the 180-degree hybrid coupler. Furthermore, the feasibility of controlling the load impedance at higher harmonic frequencies is also investigated.

Abstract
This paper presents a theoretical analysis of the load modulation conditions in a Load Modulated Balanced Amplifier architecture as a function of the type of hybrid coupler employed. In particular, two cases are examined: the 90-degree hybrid coupler and the 180-degree hybrid coupler. Furthermore, the feasibility of controlling the load impedance at higher harmonic frequencies is also investigated.| File | Dimensione | Formato | |
