These factors heavily weigh into the cost and feasibility of using a particular amplifier in a given design. Regardless of electrical and RF performance, if an amplifier can\u2019t fit into the required footprint, the device won\u2019t be serviceable for that application. It is also important to note that some RF amplifiers will require external components for optimal performance; these parts are often well defined in a specification sheet. But, these additional external components will increase cost and RF amplifier footprint. There are also many vibration, shock, dust, and ruggedness parameters that may be necessary to consider for applications requiring higher reliability devices.<\/span><\/p>\n<p class=\"Normal1\"><span style=\"font-size: 12.0pt; font-family: 'Arial','sans-serif'; color: windowtext;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-full wp-image-489\" src=\"\/blog\/wp-content\/uploads\/2017\/03\/thermal.jpg\" alt=\"\" width=\"412\" height=\"377\" srcset=\"\/blog\/wp-content\/uploads\/2017\/03\/thermal.jpg 412w, \/blog\/wp-content\/uploads\/2017\/03\/thermal-175x160.jpg 175w, \/blog\/wp-content\/uploads\/2017\/03\/thermal-109x100.jpg 109w\" sizes=\"auto, (max-width: 412px) 100vw, 412px\" \/>Thermal dynamics are another element that must be considered when specifying an RF amplifier. The environmental factors and system factors can lead to very wide temperature ranges, as well as high peak temperatures. The maximum and recommended junction temperature of the transistors within an RF amplifier will be specified in a data sheet as a range of temperatures where the device can operate, or be stored without significant performance degradation.<\/span><\/p>\n<p class=\"Normal1\"><span style=\"font-size: 12.0pt; font-family: 'Arial','sans-serif'; color: windowtext;\">Many of the performance characteristics will also be given over temperature, which must be maintained for desired performance.
