Quel est l'usage habituel des diodes PIN?
- ACommutateur RF
- BSource de courant constant
- CRedresseur de haute tension
- DSource de tension constante
Correct answer: A — Commutateur RF. Question tirée de la banque officielle d'ISDE.
Why
A PIN diode acts like a fast electronic gate for radio frequency signals because its middle layer lets it change resistance quickly when you apply voltage, allowing it to turn high-frequency currents on or off without distortion. The full explanation — and one for every question — is in Pro.
