Making outline
- Assemble matched diode mixing arms with geometrical LO quadrature paths
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Discrete-semiconductors stock may supply diodes after grade qualification; new assembly."
