About the CapCoupler PCB
CapCoupler is an open source PCB design by F6ITU, published on GitHub. It is a 2-layer board measuring 50 × 32.5 mm, with 5 components from 4 distinct parts.
By type, the board carries 3 connectors and 2 capacitors.
From the project
Petit coupleur capacitif (ou "tap" en franglais) destiné à prélever une faible portion d'énergie dans un circuit HF de puissance.

Selon la puissance émise, les condensateurs utilisés doivent être capable de supporter entre 500 et 2000V. Capas porcelaine ou mica "cms" vivement conseillées. Caveat emptor
Comparativement aux coupleurs inductifs ou capacitifs, ce genre de montage est "relativement" indépendant de la fréquence de travail. Il est donc utilisable sans grande déterioration des performances entre 1 et 500 MHz.
