SKY13414-485LF

RF Switches Overview

The SKY13414-485LF is a single-pole, four-throw (SP4T) RF antenna switch manufactured by Skyworks Solutions Inc. It operates within a frequency range of 100 MHz to 3 GHz and features an internal 50-ohm termination for control diversity antenna impedance. The device utilizes silicon technology and is housed in a 14-QFN (2x2 mm) surface-mount package. Key electrical parameters include a typical insertion loss of 0.4 dB and a typical off-isolation of 26 dB, with a maximum isolation rating of 42 dB. It supports a supply voltage of 2.5 V to 4.8 V and functions reliably across an operating temperature range of -40°C to +85°C.

• Integrated internal 50-ohm termination to simplify control diversity antenna impedance matching
• High linearity performance characterized by P1dB of 37 dBm and IIP3 of 70 dBm
• Low insertion loss and high isolation capabilities for efficient signal routing

RF Switches Applications

• 2G/3G/4G antenna diversity systems
• LTE TDD transmit/receive systems
• LTE FDD transmit/receive systems

RF Switches Procurement Notes

Verify the specific ordering suffix and packaging format, such as Cut Tape or Reel, against the official Skyworks documentation to ensure compatibility with automated assembly processes. Confirm that the application does not require GSM transmission support, as this component is explicitly designed for systems excluding GSM transmit paths. Ensure the selected variant matches the required RoHS compliance standards for the target market.

RF Switches Selection Notes

Select this component for designs requiring SP4T switching between 100 MHz and 3 GHz with minimal insertion loss. It is suitable for LTE TDD/FDD and multi-band diversity applications where GSM transmission is not needed. Consider the 14-QFN package size for space-constrained layouts and verify that the 2.5 V to 4.8 V supply range aligns with the system's power architecture.
