The RF front-end performance suffers from changes in operating environment, like hand-effects, that are often unpredictable.\u003c\/p\u003e \u003cp\u003e\u003cem\u003eAdaptive RF Front-Ends for Hand-Held Applications\u003c\/em\u003e presents an analysis on the impact of fluctuating environmental parameters. In order to overcome undesired behavior two different adaptive control methods are treated that make RF frond-ends more resilient: adaptive impedance control, and adaptive power control.\u003c\/p\u003e \u003cp\u003eSeveral adaptive impedance control techniques are discussed, using a priori knowledge on matching network properties, in order to simplify robust 2-dimensional control. A generic protection concept is presented, based on adaptive power control, which improves the ruggedness of a power amplifier or preserves its linearity under extremes. It comprises over-voltage, over-temperature, and under-voltage protection.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45275292467351,"sku":"9789400799141","price":7277.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9789400799141.webp?v=1769282475","url":"https:\/\/atlanticbooks.com\/products\/adaptive-rf-front-ends-for-hand-held-applications-9789400799141","provider":"Atlantic Books","version":"1.0","type":"link"}
