Emerging 5G networks bring with them a new range of radio front end requirements that must be met by the RF front end (LNA + PA). SKY66113-11 is one such RF front end device designed to meet the complexities of 5G networks. This article examines the application field and working principle of the SKY66113-11 in order to illustrate its performance and features.

The SKY66113-11 is a multi-chip power amplifier (PA) and low-noise amplifier (LNA) combination module designed to provide end-to-end radio frequency (RF) linear gain and power control for 5G networks. The PA operates over a wide frequency range of 600 MHz to 6 GHz and provides very high linear power levels, while the LNA offers a low noise figure. The chips are connected by linear circuits which provide stability and improved efficiency. Furthermore, the device integrates reverse power detectors which enable accurate power control. This makes the SKY66113-11 an excellent solution for 5G base stations, which require extremely high linear power and low noise figures.

The operation of the SKY66113-11 RF front end device is determined by its unique working principle. The LNA is responsible for amplifying the weak, incoming signals from the antenna while the PA amplifies the outgoing signals. The two chips are connected via a power measurement block which accurately monitors the power consumption of the device. This allows for precise power control by adjusting the current supply to the PA. The power of the receive and transmit signals are also monitored in order to ensure that the device is operating within the required power range. In addition, the protective diode circuitry is used to protect the device form unexpected high power input signals.

The SKY66113-11 is an excellent device for 5G RF front end applications. It combines a powerful PA with a low-noise LNA in order to provide high linear gain and power control. Furthermore, its unique power measurement block and protection circuitry enables it to operate reliably in high power RF applications. By understanding its application field and working principle, we can better appreciate its performance and features.
