[introduction] the article uses Smith the design manual that round figure matchs as RF impedance. Gave out to reflex the constructive example of coefficient, impedance and admittance in article, gave out the constructive example that MAX2472 works to match a network when 900MHz.   The fact proves, graph of Shi Mi Si Yuan remains the main tool of impedance of firm transmission line.   When the actual application issue that handles RF system, total meeting encounters the job of a…

[introduction] common static model has: Mannequin (HBM) , bring model of electric parts of an apparatus, field induction model, enhance a model, machine model and capacitance coupling model. Chip class does a test with HBM commonly, and the discharge model that electronic product uses IEC 6 1000-4-2 does a test. To undertake unity a standard to the test of ESD, in industrial standard field, europe in all the IEC 61000-4-2 of body already built strict twinkling to change concussion controls…

[introduction] BMS(Battery Management System) is batteries of component of core of car of join new energy resources and truckload bridge. The development of car of new energy resources of benefit from benefit from, the BMS that regards core as the component also got flying development. BMS differs according to pilot structure cent is BMS of type of principal and subordinate and BMS of machine of an organic whole. No matter which kinds control a construction, it is indispensable that total…
