RF Transceiver ICS Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verify end-of-life status and lead times carefully before integration into new designs. Sourcing should focus on remaining inventory or authorized surplus channels, as direct manufacturing supply has ceased.

RF Transceiver ICS Selection Notes

Select this part only for legacy system maintenance or specific ISM band requirements where its 27-930MHz range and ASK/FSK capabilities are necessary. Consider the obsolete lifecycle status when planning long-term production. Ensure compatibility with the 32-VFQFN package footprint and verify that the 115 kb/s data rate meets application throughput needs.

RF Transceiver ICS Part Context

Part of the TH7122 series, this transceiver integrates transmitter and receiver functions in a single chip. It is designed for cost-effective wireless solutions in the sub-1GHz range. The silicon-based construction ensures standard industrial reliability. As an obsolete item, it represents a previous generation of Melexis RF integrated circuits for general-purpose wireless applications.

RF Transceiver ICS Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, engineers must evaluate alternative modern transceivers from Melexis or other manufacturers that offer updated packages and supported lifecycles while matching the required frequency and modulation specifications.
