SKY13399-468LF

RF Switches Overview

The SKY13399-468LF is a dual-pole triple-throw (DP3T) RF switch IC designed for wireless applications. It operates within a frequency range of 10 MHz to 2.7 GHz. The device features low insertion loss, specified as 0.4 dB at 2.2 GHz and 0.3 to 0.45 dB across the band. Typical off-isolation is 21 dB, with some sources citing up to 60 dB. It supports control voltages from 2.5 V to 4.8 V, with a high control voltage of 2.7 V. The switch has a maximum operating time and idle time of 550 ns. Power consumption is characterized by a working supply current of 33.5 uA. The component is housed in an 18-lead QFN package (2x2 mm) and operates between -40°C and +85°C.

RF Switches Feature Summary

• Dual-pole triple-throw switching topology enables routing signals between three distinct paths.
• Low insertion loss performance ensures minimal signal attenuation in the active path.
• Silicon-based technology provides compact surface-mount integration.
• Supports standard logic control voltages for easy interface with baseband processors.

RF Switches Applications

• CDMA mobile communication systems
• GSM network infrastructure and devices
• WCDMA handset front-end modules

RF Switches Procurement Notes

Verify component authenticity through authorized Skyworks distributors or certified partners. Check for recent Product Change Notifications regarding assembly sites or material updates. Confirm RoHS compliance status against current regulatory requirements. Validate package marking and date codes against official manufacturing records. Ensure storage conditions meet moisture sensitivity level specifications prior to reflow soldering.

RF Switches Selection Notes

Select this DP3T configuration when signal routing between three ports is required within the 2.7 GHz limit. Consider the 0.4 dB insertion loss for power-sensitive designs. Verify that the 2.7 V high control voltage aligns with available system logic levels. Evaluate the 18-QFN footprint against PCB space constraints. Compare isolation requirements against application needs, noting typical values may vary.
