RF Transceiver Modules And Modems Procurement Notes

Verify the specific package variant matches the required interface configuration. Confirm that the U.FL connector type aligns with the intended antenna selection. Ensure the voltage supply range of 2V to 3.6V fits the target system design. Check RoHS3 compliance status if environmental regulations apply. Validate the through-hole mounting requirements against the PCB layout specifications.

RF Transceiver Modules And Modems Selection Notes

Select this module when an IEEE 802.15.4 compliant solution with integrated operating system is required. The through-hole DIP package suits prototyping or applications where surface-mount space is not constrained. Consider the 20dBm output power for extended range needs within the 2.4GHz band. Evaluate the available serial interfaces against the host microcontroller capabilities.

RF Transceiver Modules And Modems Part Context

This component belongs to the Synapse Wireless SNAP family of radio modules. It utilizes the ATmega128RFA1 chip for processing and RF functions.
