• Integrated low-IF architecture enables high performance with minimal external components.
• Optimized for low current consumption across transmit and receive modes.
• Includes integrated synthesizer and programmable filter for flexible channel spacing.

RF Transmitter Applications

• Wireless sensor networks
• Remote control systems
• Telemetry applications

RF Transmitter Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches project requirements, as variations may exist. Check for obsolescence status, as this part may be discontinued for new designs. Ensure compliance with RoHS3 standards and verify packaging type against production needs.

RF Transmitter Selection Notes

Select this component for applications requiring sub-GHz transmission with moderate output power. Consider the 20-VFQFN package size for space-constrained PCB layouts. Evaluate power supply constraints against the 1.8V to 3.6V operating range. Compare against receiver-capable variants if bidirectional communication is required.

RF Transmitter Part Context

This part belongs to the Si406x family of high-performance, low-current transmitters. It shares architectural similarities with other EZRadioPRO devices but is specifically configured as a transmitter-only solution. The B0B suffix indicates specific pinning and configuration options within the broader product line.

RF Transmitter Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult official Silicon Labs resources for end-of-life management or recommended alternatives if this component is no longer suitable for new designs.
