Abstract

The invention provides a power combiner based on a slot line-grounding coplanar waveguide structure, and the power combiner comprises at least four coupling structures disposed on a substrate, and each coupling structure comprises a first slot line and a first grounding coplanar waveguide disposed on the first slot line; the second slot lines are respectively connected with the at least four coupling structures; the second grounding coplanar waveguide is connected with the second slot line; wherein the first slot line, the first grounding coplanar waveguide and the second slot line form a first-stage impedance inverter, and the second slot line and the second grounding coplanar waveguide form a second-stage impedance inverter. The invention further provides an equivalent circuit, a terahertz Doherty power amplifier and application of the terahertz Doherty power amplifier.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, in particular to a power combiner based on a slot-ground coplanar waveguide structure, an equivalent circuit, a terahertz Doherty power amplifier and applications thereof. Background technique [0002] Terahertz (THz) waves generally refer to electromagnetic waves with a frequency in the range of 0.1-10 THz (wavelength of 3000-30 μm). With the rapid development of wireless communication systems, in order to meet the data rate requirements above 100+Gbps, the development and utilization of terahertz frequency bands have been greatly promoted. The terahertz frequency band has a wide range of available spectrum resources, and has the characteristics of short wavelength, strong anti-interference ability, and penetrability. It has great application prospects in short-range and backhaul high-speed communications. In recent years, the rapid development of silicon-based semiconduct...
