SKY65338-21 RF Front End (LNA + PA)

The SKY65338-21 is an integrated RF front end product from Skyworks Solutions Inc., a leading supplier of RF and analog front ends for the automotive, industrial, broadband, and wireless communications markets. It is designed for operation between 2150 MHz and 2350 MHz and consists of an integrated low noise amplifier (LNA), power amplifier (PA), and switched filter for front-end applications.

Features and Benefits

SKY65338-21 offers several features and benefits that make it an ideal choice for front-end applications. This integrated solution provides low noise figure (NF) of 11 dB, a power gain of 15 dB, and an excellent output power, specifications that are generally offered by single- or dual-stage solutions. In addition, a low control voltage of 1.8 V helps to reduce the solution\'s power consumption. Moreover, the device offers a single-ended, 50 Ohm termination, eliminating the need for external reactance components. Other features include good linearity (ACLR of 38 dB), high gain control range (up to 20 dB), and wide dynamic range.

Application Field

Given its features, the SKY65338-21 integrated front-end solution can be used in a variety of applications.It is ideal for base station amplifiers that require excellent performance at a high power output, and for wireless infrastructure applications such as Wi-Fi and cellular base station amplifiers. Moreover, the device is applicable for wireless communications used in industrial, medical, and automotive applications, as it is compliant with the most advanced standards and requirements. In addition, the device can be used for broadcast applications such as digital radio, satellite broadcasting, and cable TV.

Working Principle

The SKY65338-21 is a highly integrated RF Front End. It is comprised of an LNA, PA, and switched filter. Working together, these components allow the device to provide a high power output with an excellent linearity output, low power consumption, and low noise figures.The input signal is first amplified by the LNA, which offers a low noise figure. This allows the signal to be amplified with minimal distortion. The signal then passes through the switched filter before being amplified by the PA. The filter is designed to filter out any unwanted signals that may be present, ensuring a clean, high-quality signal. The PA then amplifies the signal so that it is powerful enough for broadcasting.

Conclusion

The SKY65338-21 is a highly integrated RF Front End solution. It provides low noise figures, excellent linearity, and wide dynamic range, making it an ideal solution for base station applications that require high performance. Additionally, the low power consumption and single-ended, 50 Ohm termination make it an ideal choice for applications in wireless and broadcast communications. Finally, the device is compliant with the most advanced standards and requirements, making it suitable for use in a variety of applications.
