Problems solved by technology

However, the broadband of Chuanrong's power divider is limited by the low-end isolation of the frequency band. The solution is to increase the number of stages, but the increase in the number of stages brings insertion loss.

Abstract

The invention provides a microwave broadband power divider, which comprises multiple stages of Wilkinson power dividers. The multiple stages of Wilkinson power dividers are connected via transmission microstrip lines. Each Wilkinson power divider comprises an isolated resistor and matching capacitors. Two ends of each isolated resistor are connected with the matching capacitors respectively. The isolated resistors, the matching capacitors and the transmission microstrip lines are integrated on a GaN substrate. The transmission microstrip line comprises an input transmission line, a jagged transmission line and an output transmission line connected in sequence, wherein the input transmission line is connected with a former-stage Wilkinson power divider, and the output transmission line is connected with a post-stage Wilkinson power divider. Stages of the Wilkinson power dividers can be reduced, and a high frequency band can be achieved.

Description

technical field [0001] The invention relates to the technical field of microwave devices, in particular to a microwave broadband power divider. Background technique [0002] Microwave power divider is a multi-port microwave device, which divides the power of one microwave signal into multiple microwave signals equally or unequally, and is widely used in various wireless communication, radar, microwave measurement and other equipment. Wilkinson power divider is a relatively common microwave broadband power divider, which can be easily implemented on a planar circuit by using a microstrip structure, and is suitable for occasions with low broadband requirements. [0003] In the microwave system, the insertion loss is required to be as small as possible to reduce the energy loss of the system, and the amplitude and phase of each branch are required to be consistent, so as to ensure the high-level distribution and superposition of microwave signals. At present, with the developm...
