Institute of Radio Engineers】 【weak content of the work (For in radio frequency design work friends attention)】.

<br> <BR> content of the specific work of RF engineers, what does? .Nothing less than the following: 1. Circuit analysis, and some communications equipment company projects, the RF engineer responsible for the entire RF system, circuit, system analysis, system design guidance indicators, allocation unit module indicators, standard EMC design principles put forward .functional and performance requirements with attachments, etc.; 2. circuit design, including the block diagram of the design and circuit design, which is the RF engineer must have the basic skills. .This is also an extension from the system, and how to achieve system design goals, that is, circuit design purposes, it is also the selection of assessment devices, "causes", because the process of designing a circuit is a device selection process. .3, device selection and evaluation of the circuit to achieve the target, select the appropriate device is essential to this process and circuit design is in fact the same time. .How to choose the appropriate device, compared with the same type of device in which a more appropriate design of our products? .Cost, performance, process requirements, packaging, supplier quality, delivery, etc., but also factors to be considered. .4. Software simulation, whether ADS, MWO, Ansoft, or CST, HFSS, anyway, you gotta be one or two simulation software use it. .Simulation software can not let your design to achieve hundred percent accuracy, but the overall design will not let you deviate from the basic direction, at least they are qualitative aspects of the simulation is accurate. .So we must learn to use one to two kinds or more kinds of simulation software, and its basic role is to allow you to analyze your qualitative design, the error is always there, but it can boost your confidence. .5. PCB LAYOUT, theoretical basis of the principle is like, a million applications can only be based on a theory, there may be only a few products, a schematic, wiring as long as it's not the same, like mobile phones, with a lot of companies have used cell phone program .design, schematic is the same, but different companies out of the PCB board is not cloth, as one is not the same shape, one is a difference in performance. .Performance difference, in fact, differences in PCB LAYOUT. .Meet the requirements of the PCB, both its layout and routing performance, appearance, technology, EMC and so on. .Therefore, PCB LAYOUT is also a very important skill. .6. Debug analysis, debugging and production debugging is not the same. .Production debugging is prescriptive, the focus of R & D product is found to debug and solve problems. .Debugging is a summary of the process and gain experience, not to say that debugging through the debugger to the accumulation of experience, but to accumulate experience in the design through debugging; a lot of problems in the design could not be found, then by commissioning its discovery, to know that in the design of future .how to avoid these problems, how to improve these problems. .Debugging is a theory of practice the most effective way, we can qualitatively understand the debugging process theory. .7. Test, in fact, test the service for the commissioning and commissioning for design services (design services for the market). .RF Engineer must be familiar with using a variety of RF test equipment, regardless of spectrum analyzers, network analyzers, signal sources, oscilloscopes, power meters, noise figure testers, Tester and so on. .Does not test very difficult to effectively debug the problem can not be found how to improve it? .So do not underestimate testing technology, in fact, RF companies look abroad, the real masters are designed to test technology from the middle of the reasons worth thinking about. .8. If you can, you more than themselves, to do more grassroots work, to own their own welding to weld it, you can not find someone to debug when you stay at your side for capacitors and inductors for you? .So, do not look down Yangaoshoudi welding, the ability of their own welding it..
