SI4463-C2A-GMR
Silicon LabsSI4463-C2A-GMR is an EZRadioPRO sub-GHz transceiver from Silicon Labs in a QFN-20 4x4 mm package, covering 142 MHz to 1050 MHz with transmit power from -20 dBm to +20 dBm, -124 dBm receive sensitivity, FSK data rates up to 1000 kbps and OOK up to 120 kbps, hosted over SPI; the C2A code is the current device revision and GMR denotes the QFN-20 tape-and-reel variant. The wide frequency coverage and flexible modulation support proprietary protocols for metering, security and industrial telemetry on one radio platform, and the high sensitivity extends range at low data rates where link budget matters most. Selection advice: pick SI4463-C2A-GMR when a proprietary sub-GHz protocol needs configurable data rate and output power across several regional bands; confirm the exact C2A revision code on the BOM rather than the base SI4463 name, since ordering variants differ in revision and packing. Parameters verified against Silicon Labs documentation.

SI4463-C2A-GMR FAQ
What should I check before substituting SI4463-C2A-GMR with another Sub-GHz RF transceiver?
Match the full ordering code, not the series name: package (QFN-20 4x4 mm), temperature grade and packing all ride on the suffixes. A same-series code in a different package is a different orderable device, so confirm the substitute against the Silicon Labs datasheet before changing the BOM.
