Fully integrated 2.4 GHz and 5 GHz 802.11ax FEMs
These fully-integrated FEMs feature a logarithmic power detector supporting wide dynamic ranges and low power consumption enabling improved thermal management. They also deliver industry leading efficiency, which is ideal for POE applications.
The SKY85330-21 is a complete 802.11b/g/n/ac/ax 1024 QAM WLAN RF front-end module (FEM. The device provides all the functionality of a fully matched power amplifier (PA), power detector, low-noise amplifier (LNA), and single-pole, double-throw (SPDT) switch. The FEM provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antenna, and from the antenna to the input of the transceiver. The LNA increases the receive sensitivity of embedded solutions to improve range or to overcome the insertion loss of cellular filters (often included for mobile applications). The SKY85330-21 also includes a transmitter power detector with 20 dB of dynamic range, and a digital enable control for transmitter power ramp on/off control. It is provided in an ultra-compact, 16-pin 2.5- x 2.5-mm Quad Flat No-Lead (QFN) package.
The SKY85748-11 is a highly integrated, 5 GHz front-end module (FEM) incorporating a 5 GHz single-pole, double-throw (SPDT) transmit/receive (T/R) switch, a 5 GHz low-noise amplifier (LNA) with bypass, and a 5 GHz power amplifier (PA) intended for mobile/portable 802.11ax applications and systems. The integrated logarithmic power detector provides closed-loop power control within the system. The device is provided in a compact, 16-pin 2.5- x 2.5-mm Quad Flat No-Lead (QFN) laminate package.
Both FEMs can be paired with leading enterprise 802.11ax reference designs.
