SKY66100-11 is an integrated front-end module specifically designed to target cellular applications. This RFFE device perfectly combines a low-noise amplifier (LNA), a power amplifier (PA) with a highly efficient switch and a filtering network into one compact and cost-effective module.

Applications

SKY66100-11 can be used in different frequency bands, such as LTE/GSM/UMTS/CDMA Cellular bands. It is specialized for LTE, GPS, UMTS and GSM applications, targeting low power consumption in small formats. It features competitive gain and highly linearity, bringing better performance to mobile handsets.

Performance

SKY66100-11 provides a gain of 32 dB, with excellent linearity and low power consumption of only 4.5 mA at 3.8V in receive (Rx) mode; 19 mA at 3.8V in transmit (Tx) mode. Highly efficient division duplexer can help to filter out the frequencies away from the desired one, providing better noise cancellation and image rejection.

Working Principle

SKY66100-11 is an integrated RF front-end module, with an LNA and a PA connected through a switch. The LNA’s job is to amplify the incoming signal with a low noise figure, while the PA is responsible for providing the power necessary for transmission of the signal. The switch will switch off the PA while the receiver is receiving and power up the PA during the transmission mode.

The device is designed to work in a specific frequency band, so a filtering network needs to be added to reduce the signal interference from the out of band. The module also features a high linearity, which helps to increase the data rate of the receiver and avoid severe distortion of the signal.

Conclusion

SKY66100-11 is an efficient and integrated RF front-end module with excellent linearity and low power consumption, making it an ideal choice for mobile handsets, for LTE, GPS, UMTS, and GSM applications. The combination of LNA, PA, and filter ensures that the receiver and transmitter function efficiently without interference from out of band signals. This module is designed for the most cost-effective cellular solution, providing enhanced performance and reliability.
