{"product_id":"multidimensional-measurements-von-hibah-al-tahir","title":"Multidimensional Measurements","description":"\u003cp\u003eThis book describes a measurement system that was set to perform comprehensive measurements on RF power amplifiers. Data obtained from the measurements is then processed mathematically to plot 3-D graphs of the basic parameters affected or generated by nonlinearities of the amplifier i.e. gain, efficiency and distortion .Using a class AB amplifier as the DUT, two sets of signals ¿ both swept in power level and frequency - were generated to validate the method; a two-tone signal and a WCDMA signal. The measurement setup yields 3-D plots of variations of gain, efficiency or distortion versus any arbitrary range of frequencies and input levels. Moreover, the measurement tool can be used to plot traditional 2-D plots.  The test signals were generated by computer then sent to a vector signal generator that generates the actual signals fed to the amplifier. The output of the amplifier is fed to a vector signal analyzer then collected by computer to be handled. MATLAB® was used throughout the entire process.  The system can be a very useful tool for RF amplifier users and designers. It is also useful for students who are working to understand RF amplifiers and their common trade-offs.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838390857\"\u003e\u003ch3\u003eon RF Power Amplifiers\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838390857","offer_id":39469278462045,"sku":"9783838390857","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/41a472dd-54a0-415e-aab0-1ccdca6ca8b2.jpg?v=1758087241","url":"https:\/\/shop.autorenwelt.de\/products\/multidimensional-measurements-von-hibah-al-tahir","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
