Small, short life and cost are higher；The latter's shortcoming is that insertion loss is larger, volume is big and power consumption is larger.
The content of the invention
In view of this, the utility model is directed to a kind of high-power hilted broadsword of the high-power signal of controllable radio-frequency channel
Double-throw radio frequency switch device.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of single-knife dual-close large power radio frequency switch device, it is characterised in that：Including communication link one, the and of communication link two
Control converting unit, described communication link one mainly by the first blocking unit and first switch unit, the second blocking unit and
Second switch unit forms；Described communication link two is mainly single by the first blocking unit and first switch unit, the 3rd switch
Member and impedance matching unit composition；
The first described blocking unit couples with first switch unit, the second blocking unit and the coupling of second switch unit,
3rd switch element and impedance matching unit coupling；First switch unit, second switch unit, the 3rd switch element with control
Converting unit connects.
Described communication link two also includes the 4th switch element and the 3rd blocking unit, and control converting unit is opened with the 4th
Close unit connection, the 4th switch element and the coupling of the 3rd blocking unit.
Further, the described match circuit power of communication link one is not less than 200W, is lost close to 0.1dB.
Further, the described match circuit isolation of communication link two is not less than 70dB.
Further, described switch element is mainly made up of switching tube and direct-current short circuit device.
Further, described impedance matching unit uses flexible radio frequency cable.
Relative to prior art, a kind of single-knife dual-close large power radio frequency switch device described in the utility model has following
Advantage：The utility model is applied to the RF switch of high-power (more than 200W) signal control, is ensureing less loss basis
Under (0.1dB), improve switch to bear power simultaneously rational in infrastructure, reduce production cost, the utility model PCB layouts are closed
Reason, it is stable.

Unit is connected with switch element 4, and switch element 4 and blocking unit 3 couple.The switch element adopted is mainly by switching tube and straight
Flow short-circuit device forms.Described impedance matching unit uses flexible radio frequency cable.
Communication link one is by emulating, optimizing and later stage debugging provides low-loss and higher bears power；Communication chain
Road two is by emulating, optimizing and later stage debugging provides higher isolation between low-loss and two-way.Described blocking list
Member is protected for port input and output, prevents control voltage from causing to damage to output port, while input and output is matched 50 Ω
Load.Described impedance matching unit act as improving two-way isolation, and impedance matching unit uses flexible radio frequency cable, passed through
The experimental data obtained after artificial debugging, described direct-current short circuit device are that the conversion voltage leak for preventing conversion control circuit arrives it
His unit.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
