SKY13321-360LF

RF Switches Overview

The SKY13321-360LF is a pHEMT GaAs FET single-pole double-throw (SPDT) RF switch designed for operation within the 0.1 GHz to 3.0 GHz frequency range. It features a low insertion loss of 0.4 dB and utilizes an 8-pin QFN package. The device supports transmit/receive applications by connecting the common port (RFC, pin 7) to the signal path. Operating temperature specifications range from -40°C to +85°C. This component is currently classified as obsolete and is not recommended for new designs.

RF Switches Feature Summary

• Utilizes pHEMT GaAs FET technology for high-performance RF switching
• Provides low insertion loss characteristics suitable for signal integrity
• Supports SPDT topology with reflective circuit design

RF Switches Applications

• WiMax systems
• Transmit/Receive (T/R) modules
• RF signal routing in wireless infrastructure

RF Switches Procurement Notes

Verify component status carefully before procurement planning. The SKY13321-360LF is officially listed as obsolete and discontinued by Skyworks Solutions. It is explicitly not recommended for new designs. Sourcing should focus on existing inventory or qualified replacement alternatives rather than new manufacturing orders. Confirm end-of-life documentation and availability constraints prior to integration into any production schedule.

RF Switches Selection Notes

Consider the obsolete status when selecting this component for new projects. Evaluate successor models or alternative SPDT switches that offer current manufacturing support. Ensure compatibility with the required 0.1-3.0 GHz frequency range and QFN package footprint if replacing existing designs. Verify that performance metrics such as insertion loss meet system requirements without relying on discontinued part availability.

RF Switches Part Context

This component belongs to the Skyworks Solutions RF Switch IC family, specifically targeting WiMax and general RF applications up to 3 GHz. It represents a GaAs-based solution offering low insertion loss. The product lifecycle status indicates it has reached end-of-life, distinguishing it from active portfolio items currently supported for new design implementations.

RF Switches Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the available documentation. Due to the obsolete status, engineers must identify equivalent SPDT GaAs switches with compatible electrical parameters and package dimensions through independent technical comparison.
