1. IntroductionRF Front End, as a discontinuous element of microwave circuits, is vital in the form of amplification because it has a great influence on the overall performance. The device, SKY85300-21, is designed to meet the performance criteria, stability, linearity, and overall features for the most demanding wireless microwave communications applications. In this article, we will discuss the application field and working principle of SKY85300-21. 2. Application FieldSKY85300-21 is a high-performance, high-linearity, and highly integrated front-end module for 2.3GHz applications. It is mainly used in applications that require high linearity such as WLAN, WiMAX, WCDMA, GSM and Bluetooth. Besides, as a bridge between the antenna and the transmission circuit, it is widely used in the circuits of radar, satellite, telecommunication and industry control systems.3. Working PrincipleThe SKY85300-21 contains an integrated LNA and PA. The LNA (Low Noise Amplifier) is designed with a high input-power density and lowest noise figure to obtain a high signal dynamic range. The gain of the LNA is adjusted using a single external inductance. This makes the LNA, without using additional on-chip matching, within the linear range. The integrated PA (Power Amplifier) includes both the linear PA and the high-efficiency Class-AB PA. It is broadly adjustable with a wide range of Vcc supply voltage, heat dissipation, and output power. The gain of the PA is adjustable using a single external resistor. The following figure shows the block diagram of SKY85300-21 LNA + PA.4. ConclusionsIn conclusion, the SKY85300-21 is an advanced RF unit which is highly integrated, low power consumption and small size. It is able to provide high performance in linearity and gain, which makes it an ideal product for a variety of wireless communication applications. The module needs only two matching elements to meet all specification, which makes the device easy to use.
