SKY13351-378LF

RF Switches Overview

The SKY13351-378LF is a single-pole double-throw (SPDT) RF switch IC manufactured by Skyworks Solutions Inc. utilizing pHEMT GaAs FET technology. It operates within a frequency range of 20 MHz to 6 GHz and features a 50 Ohm impedance. Key electrical parameters include an insertion loss of 0.35 dB at 2.45 GHz and up to 0.5 dB, with typical off-isolation of 26 dB. The device supports control voltages from 1.8 V to 5 V, exhibits a maximum switching time of 100 ns, and functions within a temperature range of -40°C to +85°C. It is housed in a compact 6-MLPD (1x1) surface-mount package.

RF Switches Procurement Notes

Verify the specific suffix '378LF' against official Skyworks documentation to confirm the exact tape-and-reel packaging configuration and RoHS compliance status. Ensure that the ordered component matches the 6-MLPD physical footprint and pinout defined in the datasheet. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

RF Switches Selection Notes

Select this component for designs requiring SPDT switching capabilities across the 20 MHz to 6 GHz spectrum. It is suitable for space-constrained wireless modules due to its small 6-MLPD package. Consider the 0.35 dB insertion loss at 2.45 GHz for efficiency-critical paths. Verify that the system control logic aligns with the 1.8 V to 5 V input voltage range required for switching states.

RF Switches Part Context

This component belongs to the Skyworks SKY13351 series of general-purpose RF switches. It is designed as a direct replacement or upgrade for legacy SPDT switches in mobile and infrastructure equipment. The integration of pHEMT GaAs technology allows for superior linearity and isolation compared to standard silicon alternatives, supporting modern broadband communication standards.

RF Switches Replacement Considerations

SKY13355-374LF is a documented dual-pole double-throw (DPDT) variant within the same family, offering different topology but similar frequency ranges.
