RF Transceiver ICS Procurement Notes

This component has been officially declared obsolete by onsemi as of September 30, 2022. Procurement must rely exclusively on third-party distributors or surplus stock providers such as Rochester Electronics. Verify lot dates and storage conditions carefully due to end-of-life status. Availability is limited to existing inventory rather than direct manufacturing supply. Ensure compatibility with current design requirements before sourcing from secondary markets.

RF Transceiver ICS Selection Notes

Select this transceiver for applications demanding high output power and sensitivity in Sub-GHz bands. The wide frequency coverage supports global ISM band compliance. Consider the 28-QFN package for compact surface-mount designs. Evaluate power consumption profiles against battery life requirements given the 255 mA transmit current. Confirm SPI interface compatibility with the host microcontroller for seamless integration into existing embedded architectures.
