SKY85601-11

Overview

The SKY85601-11 is an integrated Single-Pole Double-Throw (SPDT) switch with a Low-Noise Amplifier (LNA) designed for wireless applications. It operates within a frequency range of 4.9 GHz to 5.9 GHz. The device features a typical noise figure of 2.5 dB and provides 12 dB gain in the transmit mode. It offers 50 dB typical off-isolation and functions at a supply voltage of 3.3 V, drawing 15 mA. The component is housed in a compact 2.5x2.5 mm, 16-pin QFN package.

Feature Summary

• Integrates SPDT switching functionality with a low-noise amplifier for enhanced signal integrity.
• Includes integrated control logic to simplify system design and reduce external component count.
• Operates with low power consumption and includes shutdown capabilities to conserve energy during inactive states.

Applications

• Wireless local area network (WLAN) systems
• 5 GHz band communication devices
• Mobile broadband infrastructure

Procurement Notes

Verify current availability status as distribution channels may vary. Confirm that the specific ordering suffix matches the required package type and tape/reel specifications. Ensure compliance with RoHS directives and check for any end-of-life notifications or discontinuation updates from Skyworks Solutions prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring a combined switch and LNA solution in the 5 GHz spectrum. Consider the 16-pin QFN footprint for space-constrained PCB layouts. Evaluate the 2.5 dB noise figure and 12 dB gain against system link budget requirements. Verify compatibility with the 3.3 V operating voltage and interface logic levels used in the target application.
