Abstract
The invention discloses a kind of isolation rearrangeable switches, comprising: switch A (1), matched load (2), amplifier (3), switch B (4), coupler (5) and adjustable attenuator (6).Input signal enters coupler (5) by switch A (1) selection, adjustable attenuator (6) is coupled to by coupler (5), output signal is obtained by switch B (4) selection, or input signal directly passes through amplifier (3) through switch A (1), then obtains output signal through switch B (4) selection.The present invention solves the problems, such as that chip integrated circuit switch isolation is unadjustable.
Description
Technical field
The present invention relates to a kind of switch, especially a kind of isolation rearrangeable switch.
Background technique
The switch designed in the past is made of switch chip, and switching circuit isolation is determined by switch chip index itself, nothing
Method is adjusted, and is unable to satisfy requirement in the case where having adjustable require to isolation.
Summary of the invention
It is an object of that present invention to provide a kind of isolation rearrangeable switches, and solving chip integrated circuit switch isolation can not
The problem of adjusting.
A kind of isolation rearrangeable switch, comprising: switch A, amplifier, switch B, further includes: matched load, coupler and can
Controlled attenuator.
Input signal end is connect with the input terminal of switch A, two output ends of switch A respectively with the port of coupler 2 and
One end of amplifier connects, and the other end of amplifier is connect with an input terminal of switch B, another input terminal of switch B and
One end of adjustable attenuator connects, and the other end of adjustable attenuator and the port 4 of coupler connect, the port 1 of coupler with
It is connected with load, the port 3 of coupler is connected to ground, and the output end of switch B is connect with output signal end.
Further, the resistance value of the matched load is 50 Ω.
Further, input signal enters coupler through switch A selection, is coupled to adjustable attenuator adjustment by coupler and declines
After degree of subtracting, select to obtain output signal by switch B.
Further, input signal directly adjusts power by amplifier through switch A, then selects to be exported through switch B
Signal.
Isolation rearrangeable switch of the present invention is by increasing coupling attenuation branch, and attenuator pad value is adjustable, to realize
Switch isolation degree it is adjustable, when receiving big signal, switch isolation degree can be improved according to received signal strength, after protection
Grade circuit is not entered saturation region or burns, and leads to not work.
