High Power Frequency Hopping Filter

Nowadays the military communication mode is gradually turning from point to point intonetworking. Each single equipment is corresponding to each sub-node.Each sub-node usuallycontains more than one same type of equipment or others. Since the application mode，theperformance index of the equipment,especially the ability of anti-interference,has beenenchanced a lot. The subject mainly does research in UHF high power frequency hoppingfilter.The filter is also been called the Same-address filter. Its exsisting allow more than oneequipments working together at the same location.The anti-interference of the equipment ismainly decided by the performance of the filter.The Same-address filter which this subject researched uses the method of combinatingcavity resonator and parallel capacitance. Comparing to the traditional filter，it has theadvantages of stronger anti-interference abilities，smaller volume，lower insertloss，higherpower in design and easier to produce，simpler to test in manufacture.The main work of the subject contained：1. Declared the importance of this subject in the entire project，analysised the currentsituation of domestic and abroad，discussed the key technology and new views.2. Proceed from the reality, I exhibited the main parameters and basic mode of the filter,depicted transforms of different types of filter.3. Based on the demand of the project，I used the method of simulation to determine thestage,the type of coupling and the final form of the filter.4. Decided to use the structure of coaxial cavity，I obtained the result of each parts andthe whole body of the filter by CST.It paved steady basis for later manufactures.5. Next，I gave the progress of manufacture and assembling. After debugging and solvingthe problems explosed, I showed the improvement and identified the result. Finally，I sumedup the experience and left much to be desired.
