What is BS EN 62604-1- SAW and BAW duplexers of assessed quality about?
BS EN 62604 is an international standard that discusses surface acoustic wave (SAW) and bulk acoustic wave (BAW) duplexers of assessed quality, ensuring operational stability and longevity in duplexers.
BS EN 62604‑1 is the first part of the BS EN 62604 series that specifies the methods of test and general requirements for SAW and BAW duplexers of assessed quality using either capability approval or qualification approval procedures.
Who is BS EN 62604-1- SAW and BAW duplexers of assessed quality for?
BS EN 62604-1 on SAW and BAW duplexers are useful for:
- Manufacturer of piezoelectric devices
- Manufacturer of surface acoustic wave devices
- Manufacturer of bulk acoustic wave devices
- Manufacturer of electronic communication devices
- Telecommunication industry
- Quality testing personnel
Why should you use BS EN 62604-1- SAW and BAW duplexers of assessed quality?
Duplexer characteristics are usually expressed in terms of center frequency, pass bandwidth, and insertion attenuation for each of transmitting and receiving filter parts in the duplexer and isolation level between the transmitter and receiver ports. SAW and BAW duplexers are used in the RF front-end of the user equipment, lower insertion attenuation, higher isolation/rejection level, stronger power durability, and smaller/thinner package dimensions are strictly required.
BS EN 62604-1 provides users guidance on preferred values for ratings, marking, quality assessment procedures, test and measurement procedures, ensuring quality and performance in duplexers.
BS EN 62604-1 provides users guidance on test and measurement procedures, including test and measurement conditions, visual inspection, dimensions test, electrical test procedures, mechanical and environmental test procedures, and endurance test procedures, ensuring operational safety and stability of SAW and BAW duplexers.
Adopting the BS EN 62604-1 guideline for use of SAW and BAW duplexers plays a positive role in quality management systems.
