  7. Together with the test of its basic performance, a programmable filter using the designed chip and two saw filters, whose center frequency and bandwidth can be adjusted, is also built and tested. the test results show that, the minimum insertion loss is - 5. 2 - 10. 5db, with the maximum isolation loss lying between - 40. 5 - - 23. 4db, and the maximum continually tunable dynamic range is 21. 3db, from 50mhz to 250mhz

    測試結果表明：在50 250mhz的工作頻段內，該電路導通時最小插入損耗約為- 5 - 10 . 5db ，關斷時隔離度可達- 40 . 5 - 23 . 4db左右；其連續可調的加權動態范圍最大值為21 . 3db 。
  8. Preparation and performance test of filter materials of water clarifier

    凈水器濾芯材料的制備與性能測試
  9. From the test results, we find the online event filter software, which is developed based on gaudi framework, can work properly. this will be a good foundation for the further test and performance tuning

    初步測試結果表明，基於gaudi框架開發的在線事例篩選軟體可以正常運行，為進一步的調試和性能優化奠定了良好的基礎。
  10. The filter takes the advantages of low cost, small in size, light in weight, etc., and can easily be integrated into microwave and millimeter wave integrated circuits firstly, the ltcc technology was introduced and a test circuit based on the resonate method of microstrip ring was designed to test the performance of ltcc for dielectric constant and loss

    這種濾波器具有體積小，便於集成的特點，也適用於表面貼裝。先是對ltcc工藝及材料做了基本介紹，並採用微帶環諧振法設計了一個ltcc工藝性能測試電路，對ltcc成品的介電常數、損耗和q值進行測試。
  11. The results of the test demonstrated that the system has a good performance in the linearity, dynamic scope, isolation, coherence of the amplitude. the group delay of the upmixers is 2ns, which is better than other domestic manufactures. because the inconsistency between the isolation and the phase coherence, and the error of the test method, we haven ’ t gotten the good performance of the phase coherence. the next work is improving the restrain of the filter to the lo signal and the phase test methods

    在單路發射通道上，群時延達到了2ns ，優于國內很多產品。三路通道之間的相位一致性由於測試方法的誤差以及隔離度指標的牽引作用，我們不能調試達到非常好的在相位一致性指標，再下一輪的工作中必須提高濾波器對本振信號的抑制度，改進相位測試方法以達到指標要求。
