• Design Notes: Configure channel bandwidth, bit rate and packet handling together; receiver performance depends on the programmed modem settings.

Applications

433 MHz, 868 MHz and 915 MHz remote controls, smart metering receivers, home automation and wireless sensor receiver nodes.

Proprietary ISM receiver designs needing a programmable receive chain with fewer external RF components.

Quality & Sourcing

Antrex Electronics can support sourcing for SX1239IMLTRT through available stock checks, BOM consolidation and alternative-lot review. For RF receiver components, packaging condition, date code, MSL handling and original labeling should be verified before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF receiver parts.
