RF amplifiers, also known as radio frequency (RF) amplifiers, are devices used to amplify an RF signal. They can amplify a wide range of frequencies, ranging from the very low frequency (VLF), up to the microwave range. An RF amplifier is commonly used to extend the range of a wireless device by increasing the signal strength. Furthermore, these amplifiers are also used to increase the available range of communication between two wireless devices, or between a computer and a wireless device. In this article, we will discuss the application field and working principle of the SKY65387-11 RF amplifier.

The SKY65387-11 is an RF power amplifier designed specifically for PA applications. It operates in the 2.4GHz frequency band, providing both superior linearity and efficiency. The amplifier can deliver up to 24 dBm average output power. The amplifier also offers excellent control features, including a temperature monitor and a current-sense offset setpoint. This allows the user to better manage and monitor the performance of the amplifier.

The SKY65387-11 is designed for use in PA systems, such as Wi-Fi routers, cellular base stations, and Bluetooth transmitters. It is also suitable for other applications in the 2.4GHz frequency band that require a high level of linearity, such as microwave data links and digital and analog radio communication systems. In addition, the amplifier is also well-suited for use in HF and VHF applications.

The working principle of an RF amplifier is based on the principle of resonance. When an RF signal is applied to an antenna, the signal will be picked up by the antenna and converted into electrical energy. This electrical energy is then applied to an amplifier. The amplifier amplifies the signal and sends it out over a wider frequency range. The signal will travel until it is eventually attenuated and absorbed by other components.

The SKY65387-11 is equipped with an integrated power control circuit, which enables the device to maintain a stable output power over a wide range of temperature and supply voltage variations. Additionally, the amplifier also features built-in over-temperature protection, overload protection, and short-circuit protection for enhanced operational safety. The amplifier is designed to meet MIL-STD-461E requirements, making it an ideal choice for stringent EMI/EMC applications.

In conclusion, the SKY65387-11 is a highly efficient and reliable RF amplifier, designed for use in PA systems and other applications in the 2.4GHz frequency band. It is equipped with an integrated power control circuit, making it easy to maintain a consistent output power over a range of temperatures and supply voltage variations. As well, it features built-in protections for added operational safety. The amplifier is suitable for the most stringent EMI/EMC applications, meeting MIL-STD-461E compliance.
