Description
Technical field
The present invention relates to microwave device technical field more particularly to a kind of waveguide junction circulator power of low-power source demand
Pilot system.
Background technique
As technology is constantly updated, product power is continuously increased, and product power test requires also be continuously increased.To guarantee
The reliability of product, waveguide junction circulator need to carry out power test verifying in process of production.The continuous promotion of power demand, leads
Power test is caused to there are following several respects:
(1) lack power source: the application of waveguide junction circulator need to carry out drop volume by corresponding specification, usually require that be 75%, therefore system
Mentioned corresponding product is more than the power about 33% in system power source, therefore lacks power source frequent occurrence without can be carried out power
The case where test, is tested using original power source, and is not able to satisfy the power requirement of test determination.
(2) empirical risk with it is at high cost: power is higher, and corresponding radiating requirements are high, and the energy of consumption is also higher, test parts
Chance of failure is also higher.Further include many components, such as cable, flexible waveguide in power test system, test often because of cable or
The components such as flexible waveguide are abnormal under power and lead to test abnormality, increase the risk and cost of power test.

For it is above-mentioned lack power source in the case where, when waveguide junction circulator carries out power test, existing method mainly has
Power combining schemes and total reflection scheme, in which:
The power combining schemes are higher power to be formed, to reach pilot system to high power by multichannel power combing
Demand, pilot system block diagram is as shown in Figure 1；
Power combining schemes are since the phase that cannot be guaranteed each road signal is consistent, and the power of corresponding Overlay and actual demand is not
Unanimously, especially peak power；Since combined coefficient needs additional increase power consumption, empirical risk and cost are also increased,
Increase the influence to operator's health.
The total reflection scheme is to increase full reflected system by rear class, so that power is again introduced into waveguide junction circulator, passes through
The increase of circulator centre junction power is realized in power superposition, and pilot system block diagram is as shown in Figure 1；
Total reflection scheme by rear class be totally reflected at circulator centre junction increase power, but be totally reflected power transmission direction with
Use state is different, and since power superposition is with phase change, the power that gyromagnet substrate different location is born is different.Power examination
Real use state need to be simulated by testing, and add tight examination, but being totally reflected scheme cannot be real to the progress of the field distribution inside circulator
When monitor, the field distribution of interiors of products may exist greatly different from real use state.
