2.4 + 5 GHz WLAN FEMs for Wi-Fi Connectivity
SKY85347-11/SKY85755-11
Highly integrated, dual-band WLAN FEM solution
Product Introduction
The combination of the SKY85347-11 and SKY85755-11 provides a highly integrated, dual-band RF front-end module (FEM) solution fully optimized for 802.11ax (Wi-Fi 6) mobile and portable applications. Together, they deliver seamless transmit and receive capabilities across both the 2.4 GHz and 5 GHz bands, handling the complete RF signal path between the transceiver and the antenna.| Part Number | Frequency (GHz) | Package and Size (mm) |
|---|---|---|
| SKY85347-11 | 2.4 | 16-pin, 3 x 3 mm |
| SKY85755-11 | 5 | 16-pin, 3 x 3 mm |
Essential for Wireless Applications
- 802.11ax set-top boxes, networking, and personal computer systems
- PC cards, PCMCIA cards, mini-cards, and half mini-cards
- WLAN enabled wireless video systems
Key Features
- Comprehensive Integration: Both devices consolidate a power amplifier (PA), low-noise amplifier (LNA), single-pole, double-throw (SPDT) switch, and a power detector into a single subsystem, simplifying system design.
- 2.4 GHz Performance (SKY85347-11): Boosts receive sensitivity to extend range or overcome cellular filter insertion loss. It features digital enable control for TX power ramping and a transmitter power detector with 26 dB of dynamic range.
- 5 GHz Performance (SKY85755-11): Includes an LNA with a bypass mode and an integrated power detector that provides precise, closed-loop power control for high-frequency stability.
- Compact Form Factor: Both modules are housed in space-saving 16-pin, 3 x 3 mm packages (laminate for the 2.4 GHz device and QFN for the 5 GHz device), making them ideal for space-constrained mobile designs.
