SKY85310-21

SKY85310-21 is a Skyworks RF front-end module (FEM). It integrates key RF blocks (typical customers use include a power amplifier, TX/RX switch, and matching networks) in a single compact package to simplify design for wireless devices. It is commonly used in 2.4 GHz ISM applications (e.g., Wi‑Fi, Bluetooth, Zigbee) and provides a 50-ohm interface, bias/control pins, and a straightforward path to meet regulatory masks with reduced external components. The device is designed for a single-supply bias and external control of TX/RX states, aiding power efficiency and integration. For exact frequency range, gain, output power, isolation, package/pinout, and bias requirements, refer to the official SKY85310-21 datasheet. If you have a specific use case or band, I can summarize the relevant specs.
