The SKY77179-11 is a compact RF front-end module that combines a Low-Noise Amplifier (LNA) and a Power Amplifier (PA). It is designed to simplify the design of cellular and WLAN applications and to reduce the time-to-market of these applications. The module is optimized to provide high performance performance in both Cellular and WLAN bands; it features high gain, low noise and high linearity.

Application Field: The SKY77179-11 is suitable for a wide range of cellular and WLAN applications, including 3G, WCDMA, HSDPA, HSUPA, HSPA+, TD-SCDMA, CDMA2000, LTE, WiMAX, WLAN and DVB-H. It can also be used in WIMAX and Wi-Fi applications, such as point-to-point microwave relay systems and TDD/FDD LTE.

Working Principle: The SKY77179-11 is composed of two sections, an LNA and a PA. The LNA is designed to amplify weak signals and is optimized to provide low noise performance and high gain. The PA is designed to amplify the received signal, enabling it to be transmitted over greater distances. The LNA and PA are connected to the input and output ports of the module via RF connectors, which are placed at the bottom of the module.

The LNA in the SKY77179-11 is based on an internally matched single-ended common-source GaAs MESFET design. The LNA is optimized for high gain, low noise figure, and high linearity performance, with an integrated bypass switch to reduce standby current. The PA is based on an internally-matched, linearized discrete GaAs power amplifier. It is designed to provide high linearity, efficiency and improved power-added efficiency (PAE) with decreasing inherent distortion.

The SKY77179-11 is protected from overvoltage and overcurrent, and is also designed to provide ESD protection. The module is supplied with a 3.3V supply voltage and is rated for operation from -40 to +85°C.

The SKY77179-11 is a highly robust and reliable RF front-end module that offers high performance in cellular and WLAN applications. By utilizing a combination of LNA and PA, it enables cellular and WLAN applications to benefit from a compact yet powerful RF front-end solution.
