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..
The frequency band that detection, the positioning that mainly scientific research institutions etc. units of 1-2G frequency band use use, is actually being answered
It is relatively high to the requirement of power splitter in, it is desirable that power splitter has the function of that power distribution also has the work of transmission low-tension current concurrently
With just to the design of power splitter, more stringent requirements are proposed for this.
Summary of the invention
In view of this, being able to carry out power distribution the technical problem to be solved in the present invention is to provide a kind of remote sensing power splitter
While carry out low-tension current transmission.
