With the increase in heat dissipation from microelectronics devices and the reduction in overall form factors, thermal management becomes a more a more important element of electronic product design. Both the performance reliability and life expectancy of electronic equipment are inversely related to the component temperature of the equipment. The relationship between the reliability and the operating temperature of a typical silicon semi-conductor device shows that a reduction in the temperature corresponds to an exponential increase in the reliability and life expectancy of the device. Therefore, long life and reliable performance of a component may be achieved by effectively controlling the device operating temperature within the limits set by the device design engineers. Today Keylink is recommending two heat sinks KHSF90A and KHSF150A for your power amplifier module. KeyLink's aluminum finned heat sink specially designed to match our RF power amplifier module for heat dissipa
Recently, MIIT（Ministry of industry and information technology）approved 4.8-5.0GHz, 24.75-27.5, GHz and 37-42.5GHz band for our 5G technology research and development test. In addition to the middle and low frequency 4.8-5.0GHz, which MIIT approved before, the 8.25GHz millimeter wave is approved.Which means the millimeter will take part in 5G. Why choose the 8.25GHz millimeter wave frequency between 24.75 to 27.5GHz and 37 to 42.5GHz? Wang Zhiqin, the vice chairman of IMT-2020(5G) promote group,said in a public speech, the 20GHz-40GHz has priority for pre-commecial in high frequency communication, in the meantime, 26GHz and 28GHz, 38GHz and 42GHz can use the same set of RF device, which can be more likely to achieve globe harmonization. Recently, the. Canadian Ministry of innovation, science and economic development (ISED) is preparing to use the 28 GHz band, the 37-40 GHz band, and the 64-71 GHz band for the 5G system.Coincidentally, the RSPG also believe that the frequ
