Abstract

본 발명은 전기적 길이가 90°보다 작으며 임의로 조정이 가능한 전송선로와 정합 스터브들을 갖는 구조이므로 전체적으로 회로 크기를 줄일 수 있으며, 신호를 분배하는 주기능 뿐만아니라 스터브들에 기인한 임의의 고주파 스퓨리어스 신호 제거 및 전력 합성시 생길 수 있는 미세 위상차를 튜닝 조정할 수 있는 보조 기능까지 포함하는 새로운 형태의 하이브리드 전력 분배기를 제공하는데 그 목적이 있다.Since the present invention has an electrical length of less than 90 ° and a structure having arbitrarily adjustable transmission lines and matching stubs, the overall circuit size can be reduced, and a high frequency spurious signal due to stubs as well as a main function of distributing a signal is provided. The goal is to provide a new type of hybrid power divider that includes the ability to tune and fine tune the phase differences that can occur during removal and power synthesis.

기존의 2-way전력 분배기들을 낮은 사용 주파수 대역에서 응용할 경우에는 회로 크기가 상당히 큰편이다. 반면에, 발명된 구조는 전송선로와 정합 스터브의 전기적 특성 즉 전송선로의 특성 임피이던스와 전송선로의 전기적인 길이를 요구되는 대역폭내에서 상호 조정함으로써 회로 크기를 임의로 줄여서 구현할 수 있다. 또한, 정합 스터브들에 의한 고주파 대역외 스퓨리어스 신호들을 제거하는 효과 및 전력 합성 회로 응용시 양단 선로간의 미세한 위상차를 정합 스터브들의 미세한 튜닝으로 해결함으로서 출력 성능 향상을 가져올 수 있다.When the existing two-way power divider is applied in a low frequency band, the circuit size is quite large. On the other hand, the invention can be implemented by arbitrarily reducing the circuit size by mutually adjusting the electrical characteristics of the transmission line and the matching stub, that is, the characteristic impedance of the transmission line and the electrical length of the transmission line within the required bandwidth. In addition, the output performance can be improved by eliminating high frequency out-of-band spurious signals caused by matched stubs and fine tuning of matched stubs by resolving a minute phase difference between two end lines in a power synthesis circuit application.
