RF Transceiver Modules And Modems Procurement Notes

Verify current availability status directly with TTM Technologies or authorized distributors, as this component may be subject to factory special order requirements. Confirm RoHS compliance details and moisture sensitivity level (MSL) specifications prior to procurement to ensure compatibility with assembly processes. Cross-reference the manufacturer part number against official datasheets to validate revision levels and functional parameters before finalizing purchase orders.

RF Transceiver Modules And Modems Selection Notes

Select this module when operating specifically within the 433-434.4 MHz regulatory bands. Ensure the host system provides a compatible SPI interface and operates within the 1.8 V to 3.6 V voltage range. Consider the physical dimensions and u.FL connector type for PCB layout constraints. Verify that the required output power and sensitivity meet the specific link budget requirements of the intended application environment.

RF Transceiver Modules And Modems Part Context

This component belongs to the AIR series of wireless modules from TTM Technologies. It shares architectural similarities with other variants in the lineup, such as the A1101R08C00GM and A1101R09C00GR, which operate at different frequencies like 868 MHz and 902-928 MHz respectively. All variants utilize similar packaging and core functionalities but are distinguished by their specific frequency allocations and regional regulatory certifications.

RF Transceiver Modules And Modems Replacement Considerations

Direct substitutes include other frequency-specific variants within the same AIR series, such as A1101R08C00GR or A1101R09C00GR, provided the target application supports the alternative frequency bands. Ensure that any replacement maintains the same SPI interface, voltage range, and physical footprint to guarantee mechanical and electrical compatibility without requiring significant redesign.
