Buyer scenario
Supplier screening is not paperwork; it decides whether an offer deserves engineering time. In rf / microwave / pll / synthesizer RFQs, buyers should confirm package, suffix, date-code policy and lead time before comparing supplier offers.
Relevant RFQ examples on this site include AD9361BBCZ, SKY13416-485LF, SMP1330-005LF, LMX2581SQE/NOPB.
The risk scenario
RF and Microwave demand often looks simple in a spreadsheet, but the quote can change once package verification, delivery timing and alternative part review begin.
Before sending the RFQ
Verification steps
Risk review table
| Check | Buyer question | Action |
|---|---|---|
| Package | Does the suffix match the approved BOM? | Verify before price comparison |
| Lead time | Is the delivery date realistic? | Confirm before PO planning |
| Documents | Can the supplier share useful evidence? | Request photos for high-risk lines |
| Alternates | Has engineering approved the change? | Hold quote until reviewed |
