Frequently Asked Questions
What is receiver sensitivity and why is it important?
Receiver sensitivity is the minimum signal level a receiver can detect and process reliably. It's crucial for smart key systems as it determines communication range, reliability in noisy environments, and overall system performance.
What factors affect receiver sensitivity?
Key factors include noise figure, bandwidth, required SNR, modulation type, antenna efficiency, and environmental conditions. Proper optimization ensures maximum communication range and reliability.
What is typical sensitivity for smart keys?
Motorcycle smart key receivers typically achieve -90 to -110 dBm sensitivity for LF systems and -100 to -120 dBm for UHF systems, depending on design and requirements.
How can I improve receiver sensitivity?
Improve sensitivity by reducing noise figure, optimizing antenna design, using efficient modulation, minimizing bandwidth, implementing proper filtering, and reducing interference sources.
