RF Sourcing Guides
Convert a sourcing request into a defined purchasing specification. These guides cover China-based supply coordination, distributor evaluation, OEM LoRa purchasing and bulk or obsolete requirements.
02 /LoRa & Wireless
Select a transceiver around the existing board, host firmware, operating region and production plan. Family similarity is a starting point for investigation, not proof of compatibility.
03 /RF Performance
Read RF specifications with their conditions attached. Frequency capability, output power, receiver sensitivity, noise figure and current consumption describe different parts of a design decision.
04 /RF Front-End
Source the transmit, receive, switching and filtering functions as parts of an RF chain. The right requirement includes operating band, bias, signal conditions, package and assembly constraints.
05 /Obsolete & Alternatives
Handle a supply constraint without turning an unverified substitute into a production commitment. Distinguish a shortage, a lifecycle notice and a redesign decision.
06 /Applications
Translate an application into device requirements and purchasing questions. These are engineering and procurement scenarios, not claims of RFVero projects or customer outcomes.
Obsolete & Alternatives
Record the last approved full MPN, notice evidence, available sourcing options and the validation owner. Source review and engineering approval are different workstreams.
Use these linked English guides to define the requirement, identify sourcing risks and plan customer engineering review. The following coverage labels are topics within this collection, not claims of completed projects.
Questions covered
- RF Component Lifecycle
- Obsolete Transceiver Sourcing
- Package and Interface Compatibility
- RF Performance Comparison
- Engineering Validation Requirements
