SKYWORKS SKY85806-11

The SKY85806-11 is a complete 802.11a/b/g/n/ac Wireless Local Area Network (WLAN), RF front-end module (FEM) that provides all the functionality of a power amplifier (PA), filtering, power detector, transmit/receive (T/R) switch, diplexer, and associated matching. The SKY85806-11 provides a complete 2.4 GHz and 5 GHz WLAN RF solution, from the output of the transceiver to the antenna in an ultra-compact form factor. Designed to meet the stringent linearity conditions of the 802.11ac standard, the SKY85806-11 delivers less than 2% error vector magnitude (EVM) at the rated Alternating Current (AC) power. Designed for ease of use, all RF ports are matched to 50 Ω to simplify the layout of the printed circuit board (PCB) and the interface to the transceiver. The SKY85806-11 also includes a transmitter power detector with +20 dB of dynamic range for each transmit chain. Each power amplifier has a separate digital enable control for transmitter on/off control. The power ramp rise/fall time is less than 0.5 μs. The SKY85806-11 provides local oscillator (LO) filters for the 2 GHz and 5 GHz transmit paths. The SKY85806-11 is packaged in a small 4.0×3.0×0.8 mm, Quad Flat No-Lead (QFN) package.
