How does filter of Zhuo Shengwei MAX-SAW undertake dependability test and verify in design phase?

Filter of Zhuo Shengwei MAX-SAW basically passes property in design phase test and verify of test, environmental imitate test, thermal stability, in coordination design and combination are emulated wait for means to undertake dependability test and verify. Specific as follows:

• Overall performance checks: Answer to the frequency of filter, outside inserting loss, echo loss, belt, restrain wait for each index to have a test. Pass strict test, ensure the function of filter accords with design requirement, the design that satisfies function index only just has dependability base, the sieve singles out function not to accord with the part of the requirement, so that be opposite,the design undertakes optimizing.
• Environmental imitate checks: All sorts of ambient conditions that imitate filter encounters possibly in be used actually, undertake test of compatibility of test of high low temperature, humidity test, oscillatory test, electromagnetism wait. Undertake checking for long to filter through be below different environment, test and verify its fall in all sorts of environments whether regular job, ensure filter has stability and reliability in complex actual application environment.
• Thermal stability test and verify: Through modular group class hot coupling builds a model, analyse the function show that filter leaves in tall environment difference in temperature or setting of tall power comsumption. Optimize material thermal stability, if choose low heat the POI of coefficient of expansion or optimize IDT metal system, reduce frequency to float, raise the reliability that filter leaves in the environment such as high temperature, special apply to the setting of tall power comsumption such as high-end 5G mobile phone.
• In coordination design and combination are emulated: Undertake cooperating with designing with PA manufacturer, ability and control of PA output harmonic are checked outside the belt of filter direct and relevant, be aimed at specific frequency through be being emulated jointly paragraph do match tone actor, the systematic EVM performance that improves modular group and adjacent channel segregation are spent, contented operation quotient is higher spectrum answer is used and SA index asks, be in from filter of systematic level test and verify the dependability when working in coordination with other component.
