Description
Technical field
This utility model is related to RF application, and in particular to a kind of radio frequency amplifier.
Background technology
Existing radio frequency amplifier needs by certain operating procedure during installing and using, and operational error can make entirely to penetrate
Display system index is deteriorated, and it is to detect that this index deteriorates the equipment without specialty, affects the work of radio system
Stability, it is higher to the installation requirement of installation personnel, increased use cost.Therefore, in order to avoid present in prior art
Shortcoming, it is necessary to improvement is made to prior art.
Utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with deficiency, there is provided one kind can be improved using stable
The radio frequency amplifier of property.
This utility model is realized by following technical scheme：
A kind of radio frequency amplifier, including the input port, signal distribution circuit, signal amplification circuit being sequentially connected electrically and defeated
Exit port, also including detection circuit, analysis circuit and matching internal load, the analysis circuit respectively with it is described detection circuit and
Matching internal load electrical connection, the detection circuit and matching internal load are electrically connected respectively with output port.
Further, the detection circuit includes signal deteching circuit, voltage detecting circuit and current detection circuit.
Further, the radio frequency amplifier has multi-channel input mouth and multiple-channel output port.
Further, the radio frequency amplifier has six road input ports and 24 road output ports.
Relative to prior art, this utility model amplifies by the way that whether detection electric circuit inspection has external loading to access radio frequency
Device, determines whether to access matching internal load, realizes automatically adjusting, and improves radio frequency amplifier operation stability, reduces
Installation requirement.
Description of the drawings
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is the structure principle chart of this utility model radio frequency amplifier.
In figure：1- input ports；2- output ports；3- signal distribution circuits；4- signal amplification circuits；5- detects circuit；
6- signal deteching circuits；7- voltage detecting circuits；8- current detection circuits；9- analysis circuits；10- matching internals are loaded.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than the reality of whole
Apply example.Based on the embodiment in this utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment for obtaining, belongs to the scope of this utility model protection.
As shown in Figure 1 a kind of radio frequency amplifier of the present utility model, divides including the input port 1, signal being sequentially connected electrically
With circuit 3, signal amplification circuit 4 and output port 2, also including detection circuit 5, analysis circuit 9 and matching internal load 10, point
Analysis circuit 9 10 electrically connect respectively with detection circuit 5 and matching internal load, detection circuit 5 and matching internal load 10 respectively with
Output port 2 is electrically connected.Whether analysis circuit 9 accesses matching internal load 10 according to the detection structures shape of detection circuit 5, carries
Shoot high the operation stability of audio amplifier.
Detection circuit 5 includes signal deteching circuit 6, voltage detecting circuit 7 and current detection circuit 8.
Radio frequency amplifier has multi-channel input mouth 1 and multiple-channel output port 2.As a kind of specific embodiment, radio frequency
Amplifier can have six road input ports 1 and 24 road output ports 2.
Operation principle：Signal deteching circuit 6, voltage detecting circuit 7 and current detection circuit 8 on output port 2 whether
There is bringing onto load to be detected, then the result of detection is transferred to analysis circuit 9 and is analyzed, if analysis result does not have for outside
There is access load, output port 2 connects matching internal load 10 automatically, it is internal if analysis result has access load for outside
Matched load 10 will not connect output port.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit this utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in this utility model
Protection domain within.
