SKY85743-21

The SKY85743-21 is a Skyworks 5 GHz high-power WLAN front-end module that integrates a single-pole double-throw transmit/receive switch, a power amplifier, a low-noise amplifier and control logic in one conformally shielded package. It is designed for 802.11ax (Wi-Fi 6) access points, gateways and high-end client devices that need high output power and low receive noise in a compact radio. The module provides about 32 dB of gain and delivers roughly +21 dBm of linear output for the highest MCS rates, which is enough to build a high-performance 5 GHz radio without matching a chain of discrete components. Because the front end is tuned and characterized as a unit, the design-in effort is much lower than a discrete solution, and the shielded package gives predictable isolation and behaviour in the dense RF environment of an access point. The part runs from a single supply and includes the control logic for transmit and receive modes. Every device is factory-traceable and ships with an import declaration, a certificate of origin and RoHS documentation. BeiLuo holds this part in regional stock and our FAE team supports thermal planning, layout and bring-up.
