Mikwo ond segondè frekans pkb

Yon PCB mikwo ond se yon tablo sikwi espesyalize Enjenieri pou 300 MHz ~ 300 GHz frekans, k ap sèvi de fonksyon debaz:
1. Transmisyon siyal: pwopaje siyal mikwo ond ak pèt minim;
2. EM kontwòl jaden: Jere distribisyon jaden elektwomayetik atravè estrikti presizyon.
3. espesifikasyon kle yo
