Overview
IEC 62604-1:2022 is the International Electrotechnical Commission (IEC) generic specification for surface acoustic wave (SAW) and bulk acoustic wave (BAW) duplexers of assessed quality. It specifies the methods of test and general requirements for SAW/BAW duplexers using either capability approval or qualification approval procedures. This edition updates terminology (the term “multiplexer” was added) and treats SAW and BAW duplexers together because they share the same use cases and test requirements, especially in mobile phones and other RF applications.
Key Topics
- Scope and terminology: Definitions, units and graphical symbols for SAW, BAW, duplexers and multiplexers.
- Quality assessment procedures: Requirements for manufacturer approval, capability approval and qualification approval, including eligibility, application and granting processes.
- Test and measurement methods:
- Electrical tests: S‑parameters measurement, intermodulation distortion, insulation resistance, voltage proof.
- Visual and dimensional inspection: Visual tests (A/B) and mechanical dimension checks.
- Mechanical and environmental tests: Sealing, solderability, thermal shock, vibration, shock, free-fall, acceleration, low air pressure, damp heat, salt mist, flammability and ESD sensitivity.
- Endurance and screening: Procedures for life tests, screening, rework/repair and certified records of released lots.
- Preferred ratings and characteristics: Nominal frequency bands, operating temperature ranges, climatic categories and severity levels for bump/vibration/shock.
- Marking and documentation: Duplexer and package marking requirements and capability manuals.
Applications
- Component qualification and supplier approval: Use IEC 62604-1 to qualify SAW/BAW duplexers during procurement and supplier audits.
- Design verification and production testing: Reference for RF component test plans (S‑parameters, intermodulation) and environmental robustness verification.
- Mobile and wireless equipment: Ensures duplexers meet performance and reliability expectations in mobile phones, wireless infrastructure and IoT devices.
- Certification and quality management: Supports independent conformity assessment and traceable records for released lots.
Who Should Use This Standard
- RF component manufacturers (SAW/BAW duplexers and multiplexers)
- Test laboratories and QA teams performing capability/qualification approvals
- Procurement and supply‑chain engineers specifying RF filters for mobile devices
- Certification bodies and reliability engineers evaluating environmental and electrical robustness
