Problems solved by technology

But in the higher frequency band (12~18GHz), due to the parasitic capacitance effect of the resistor, the key performances of the existing resistive power divider, such as insertion loss and voltage standing wave ratio, will be obviously deteriorated, which seriously limits the resistive power The scope of application of the dispenser

Abstract

The invention discloses a resistance-type power divider and a manufacturing process thereof. The resistance-type power divider comprises a substrate, a resistance layer which is arranged on the surface of the substrate and located in the middle of the substrate, and a microstrip layer which is arranged on the surface of the substrate. A dielectric layer and an electrode layer are sequentially arranged on the resistance layer. The use frequency band range of the power divider is expanded by adopting a composite structure of multiple layers of films.

Description

technical field [0001] The invention belongs to the field of power dividers, and in particular relates to a resistive power divider and a manufacturing process thereof. Background technique [0002] A power divider is a device that divides one input signal energy into two or more outputs with equal or unequal energy. It belongs to passive microwave devices and is mainly used for power distribution or power synthesis. In microwave equipment such as phased array radars and multi-channel relay communication machines, power dividers are more and more widely used, and users have higher and higher requirements for the performance of power dividers. The general performance requirements are: wide frequency band, small insertion loss, small voltage standing wave ratio, high power withstand, high isolation between ports, good amplitude and phase consistency between output ports, simple circuit form, small size, etc. [0003] The common Wilkinson power dividers on the market are mostl...
