With reference to Fig. 1, a kind of microwave continuous ripple high power amplitude limiter, including microwave power bonder, microwave power detector,
Detection signal amplifier, threshold compataror, PIN switch driver, Microwave High-Power PIN Switch and PIN impulse slicer, above-mentioned
Threshold compataror uses hysteretic threshold comparator, wherein said microwave power coupler input input microwave continuous ripple or wide arteries and veins
Wide pulse signal, described microwave power coupler output is respectively connecting to described Microwave High-Power PIN Switch input and micro-
Wave power detector input, thus microwave continuous ripple or wide pulse width pulse signal enter in Microwave High-Power PIN Switch and
In microwave power detector, when microwave continuous ripple or wide pulse width pulse signal enter in microwave power detector, described micro-
Wave power detector detects this microwave continuous ripple or the power of wide pulse width pulse, and described microwave power detector outfan connects
To described detection signal amplifier input, it is defeated that described detection signal amplifier outfan is connected to described hysteretic threshold comparator
Entering end, the power signal amplitude leyel detected is sent to detection signal amplifier by microwave power detector, and detection signal is put
Power signal amplitude after the power signal amplitude leyel that microwave power detector is exported by big device will amplify after being amplified is electric
Flat be sent in hysteretic threshold comparator, hysteretic threshold comparator will amplify after the power of power signal amplitude leyel and setting
Threshold level compares, and when inputting the corresponding power threshold level that microwave signal power exceedes setting, exports control signal
To subsequent conditioning circuit, described hysteretic threshold comparator output terminal is connected to described PIN switch driver input, and described PIN switchs
Driver output end is connected to described Microwave High-Power PIN Switch input, and described Microwave High-Power PIN Switch outfan connects
To described PIN impulse slicer input, when inputting the corresponding power threshold level that microwave signal power exceedes setting, sluggish
Threshold compataror output control signal turns off Microwave High-Power PIN Switch to PIN switch driver；Described microwave power couples
Device input input microwave continuous ripple or wide pulse width pulse signal, described microwave power coupler output is respectively connecting to described
Microwave High-Power PIN Switch input and microwave power detector input, so microwave continuous ripple or wide pulse width pulse signal
In entering into Microwave High-Power PIN Switch and in microwave power detector, so it is turned off it in Microwave High-Power PIN Switch
Before, the only HIGH-POWERED MICROWAVES signal of very short time can be leaked on the Microwave High-Power PIN impulse slicer of rear class, when not having
During HIGH-POWERED MICROWAVES signal, Microwave High-Power PIN Switch is to be constantly in opening state, is in the shape to microwave signal filter with low insertion loss
State, does not affect the reception of microwave signal；
Above-mentioned threshold compataror uses hysteretic threshold comparator, is in order to avoid being exactly in when input microwave signal power amplitude
During the decision threshold level of threshold compataror, threshold compataror output can produce vibration, makes Microwave High-Power PIN Switch be in frequency
Numerous labile state turned on and off, threshold compataror controls the setting of threshold level, be according to Microwave PIN impulse slicer
Determining the power bearing ability of continuous wave, above-mentioned Microwave High-Power PIN Switch uses broadband single-pole single-throw(SPST PIN switch.
Operation principle:
When microwave continuous ripple or wide pulse width pulse high-power signal are input to microwave power coupler input, microwave power coupling
Clutch is coupled out sub-fraction microwave power, microwave power detector detect the amplitude of input microwave signal power, by
Cross detection signal amplifier the amplitude of this microwave signal power to be amplified, because microwave power bonder is only coupled out sub-fraction
Microwave power, the microwave signal power amplitude leyel of detection output is smaller, is directly inputted in threshold compataror compare
Effect is unintelligible, it is therefore desirable to the detection signal amplitude of this microwave signal power is amplified through detection signal amplifier, amplifies
After detection signal compared with threshold level by hysteretic threshold comparator, when input microwave signal power exceed setting
During corresponding power threshold level, threshold compataror output control signal turns off Microwave High-Power PIN to PIN switch driver and opens
Closing, so before high-power PIN switch OFF, the only HIGH-POWERED MICROWAVES signal of very short time is leaked to the microwave of rear class
On PIN impulse slicer, when not having HIGH-POWERED MICROWAVES signal, microwave high power signal PIN switch is always maintained at opening state,
It is in the state to microwave signal filter with low insertion loss, does not affect the reception of microwave signal, so by increasing input HIGH-POWERED MICROWAVES letter
Number detection and compare, system can automatically control high-power PIN switch turn on and off state, make the microwave continuous of input
Ripple or wide pulse width high-power signal are changed into the high-power leakage signal of burst pulse；
In the microwave continuous ripple high power amplitude limiter that this patent proposes, PIN impulse slicer microwave circuit is as in figure 2 it is shown, described

It is that the microwave continuous ripple high power amplitude limiter using this patent to propose realizes microwave continuous with reference to Fig. 3 and Fig. 4, Fig. 3 and Fig. 4
The explanation that ripple or wide pulse width high-power signal amplitude limit principle are carried out:
With reference to Fig. 3, it is assumed that being the microwave signal amplitude waveform that receives of microwave receiver A point, in figure, dotted line refers to hysteretic threshold
Two power threshold level correspondence signal amplitude comparison threshold A1 and A2 that comparator sets, T1, T2, T3 are three microwaves respectively
In the moment that signal occurs, signal 1 is microwave high power continuous wave signal, and signal 2 is Microwave Low Power continuous signal, and signal 3 is
Wide pulse width microwave high power signal；Fig. 4 is after high-power input signal amplitude is controlled by Microwave High-Power PIN Switch, defeated
Go out the microwave signal amplitude waveform of C point, owing to the amplitude of signal 1 and signal 3 is more than on-off control comparison threshold, when receiving signal
1 and during signal 3, threshold compataror output control signal turns off microwave signal high-power PIN switch to PIN switch driver, by
In amplifying from the coupling of microwave high power signal, microwave power detector detection, detection signal amplifier, export to threshold compataror
Control signal turns off to PIN switch driver, and this is to need a control time, within the control time that this section is the shortest, greatly
Power microwave signal can be leaked to rear class, the signal 1 seen in T1 and the T3 moment the most in the diagram and the narrow arteries and veins of leakage of signal 3
Rush waveform, narrow pulse widtht, tGeneral at the lus order of magnitude, it is the narrowest more good that this reveals pulse width, the width of microwave signal 2
Degree is not above the comparison threshold level of threshold compataror, and therefore Microwave High-Power PIN Switch will not be turned off by control；
Microwave PIN impulse slicer uses the design of PIN limiter tube, and microwave PIN swtich uses the design of PIN switching tube, corresponding microwave
For reception system, receiving sensitivity is key index, therefore except bearing power index, and PIN impulse slicer and switch electricity

Parameter differs greatly, although producer does not provide the resistance to pulse of switching tube MA4P504 and bears power and continuous wave bears power reference
Numerical value, but from the point of view of the most pressure, series resistance Rs, the contrast of thermal resistance index, it is clear that switching tube MA4P504 compares limiter tube
It is much bigger that the continuous wave of CLA4607 bears power capability；
Table 2 gives homologous series PIN limiter tube parameter and compares:
Table 2
Two PIN limiter tube in CLA46 series in table 2, in general traditional slicer, input microwave high power signal is cascaded limit
Width circuit amplitude limit step by step, therefore cascades the limiter tube of employing and bears power and reduce the most step by step, design by traditional slicer, logical

C, PIN switching tube PIN1, PIN limiter tube PIN2 and microstrip line, described bonder connect described PIN switching tube PIN1, described every
Straight electric capacity C is connected between described PIN switching tube PIN1 and PIN limiter tube PIN2 by microstrip line, and the effect of capacitance C is
Control signal to PIN switch plays the effect of isolation, uses the X ripple of this patent microwave continuous ripple high-power amplitude limit method design
Section amplitude limiter microwave circuit, the first order uses the Microwave High-Power PIN Switch that MA4P504 switching tube realizes, micro-in actual tests
Ripple continuous wave bears power and counts as microwave pulse amplitude limiter, reference table 2 more than 50W, second level employing CLA4603 limiter tube
According to, CLA4603 limiter tube bears power for pulsewidth 1us microwave pulse and is more than 100W, and continuous wave bears power more than 2W.Use
The microwave power bonder CR degree of coupling is designed as 23dB, under 2W continuous wave inputs, and coupling output 10mW, use detection signal to put
Big device and threshold compataror, Microwave High-Power PIN Switch turns off corresponding power threshold and is set to 2W, and Microwave High-Power PIN is opened
The turn-off time closed is 800 ns, adds that time delay is compared in detection, and microwave high power signal is revealed pulse width t and is less than 1us, at figure
It can be seen that amplitude or 50W in 4, the continuous wave signal of leakage is 2W to the maximum, all bears at second level limiter tube CLA4603
In power bracket, contrast traditional microwave continuous wave amplitude limiter, holding of the microwave continuous ripple amplitude limiter of employing this patent method design
Significantly improved by power capability；Additionally, PIN impulse slicer microwave circuit is not limited in above-described embodiment only include one
PIN switching tube and a PIN limiter tube, it is also possible to be designed to include multiple PIN switching tube and multiple PIN limiter tube, when including
