SKY85707-21

Product Overview

SKY85707-21 from Skyworks Solutions Inc. is a Wi-Fi RF front-end module used in RF front-end designs that need integrated transmit, receive, switching or low-noise signal-chain functions. This description focuses on practical RF parameters such as band coverage, PA/LNA path behavior, control requirements and package compatibility.

The exact orderable suffix should be matched before purchase because RF front-end devices often vary by band plan, pinout, reel format, qualification grade and control-state truth table.

Key Features

• Manufacturer: Skyworks Solutions Inc.
• Part Number: SKY85707-21
• Device Type: Wi-Fi RF front-end module
• RF Band / Frequency Range: 2.4 GHz, 5 GHz or 6 GHz WLAN band depending on SKY85xxx suffix
• Transmit / PA Path: Integrated Wi-Fi PA path with detector/coupler or harmonic filtering on selected variants
• Receive / LNA Path: Integrated LNA with bypass and antenna switch functions for WLAN receive paths
• Output Power / Linearity: Designed for 802.11 WLAN EVM/output-power requirements; performance and pinout vary by exact suffix
• Control / Bias: CMOS control pins for TX/RX/bypass/Bluetooth coexistence or antenna path selection
• System Impedance: 50 Ω RF interface where specified by the device reference design or data sheet
• Package / Case: Compact QFN/laminate WLAN FEM package
• Operating Temperature: RF front-end module temperature range is suffix-specific; verify industrial or automotive grade before sourcing
• Design Notes: Check 2.4/5/6 GHz band assignment, package pinout and BT coexistence port before substituting SKY85xxx devices.

Applications

802.11n/ac/ax Wi-Fi routers, client modules, gateways, tablets, set-top boxes and embedded WLAN systems.

Also suitable for engineering replacements, shortage support and BOM consolidation where the same RF band, package footprint and control interface must be maintained.

Quality & Sourcing

Antrex Electronics can support sourcing for SKY85707-21 through available stock checks, BOM consolidation and alternative-lot review. For RF front-end modules, packaging condition, date code, MSL handling, reel labeling and moisture exposure should be checked before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers reduce risk when sourcing hard-to-find or lifecycle-sensitive RF front-end components.
