SI4060-B1B-FMR

RF Transmitter Overview

The SI4060-B1B-FMR is a sub-GHz RF transmitter IC from Silicon Labs, operating within the 142 MHz to 1.05 GHz frequency range. It supports data rates up to 1 Mbps and delivers an output power of 20 dBm. The device functions on a supply voltage of 1.8 V to 3.6 V with a transmission current of 85 mA. It utilizes a 20-VFQFN package with exposed pad for surface mount installation.

RF Transmitter Feature Summary

• Integrated sub-GHz transmitter optimized for low-power wireless applications
• Supports standard modulation schemes including FSK, GFSK, and OOK
• Designed for direct PCB antenna integration without external baluns

RF Transmitter Applications

• Wireless sensor networks
• Remote control systems
• Industrial telemetry

RF Transmitter Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing site changes documented in Product Change Notices. Ensure the ordering suffix matches the required tape and reel configuration for automated assembly processes.

RF Transmitter Selection Notes

Select this component when only transmission capability is required rather than full duplex communication. Consider the 20 dBm output power for extended range needs compared to lower-power variants. Evaluate the 85 mA transmission current against system battery life requirements and thermal management constraints during continuous operation.

RF Transmitter Part Context

This part belongs to the EZRadioPRO family of wireless transceivers. It shares architectural similarities with the SI446x series but lacks receiver functionality. It serves as a cost-effective solution for simple point-to-point or star network topologies where bidirectional communication is not necessary.

RF Transmitter Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing firmware and antenna designs if considering alternative models from the same product family.
