Technical field
The present invention relates to power splitter technical field more particularly to a kind of flat cavate chamber power dividers.
Background technique
Power splitter full name power divider, be it is a kind of will all the way input signal energy be divided into two-way or multiple-channel output it is equal or
The synthesis of multiple signals energy can also be exported all the way in turn, can be also referred to as combiner at this time by the device of unequal energy.One
It should ensure that certain isolation between the output port of power splitter.Power splitter is generally divided into an one-to-two (input two by output
A output), one point three (one input three output) etc..Power splitter important technological parameters power loss (including insertion damage
Consumption, distribution loss and reflection loss), the voltage standing wave ratio of each port, isolation, amplitude balance between power distribution port,
Phase balance, power capacity and frequency bandwidth etc..
Current power splitter is mostly circle, and when carrying out signal transmission, radiofrequency signal is transmitted to all directions, transmission
It is lost larger.
