Module type sensor for detecting voltage and current of radio frequency signal on PCB transmission line

A module type sensor for detecting a voltage and a current from a radio frequency (RF) signal, comprising:

• a printed circuit board on which a transmission line is printed such that the RE signal flows through the transmission line;
• a casing configured to be installed on the printed circuit board, and including:
• a casing upper surface portion which finishes an upper surface,
• a first casing side surface portion which is bent downward from the casing upper surface portion to form one side surface portion and has a lower end upwardly separated with respect to a path through which the transmission line passes,
• a second casing side surface portion which is bent downward from the casing upper surface portion to form the other side surface portion, and has a fixing bracket extending by being bent toward an outside at the lower end, and
• casing fixing means configured to fixedly lock the casing on the printed circuit board;
• a body unit configured to be fixedly installed inside the casing, formed of an insulator, and having, at a center, an opening which is open toward the transmission line;
• and
• a sensing substrate unit configured to be fixedly installed on an upper portion of the body unit, and including a voltage sensing circuit part which is capacitively coupled to the transmission line exposed through the opening and a current sensing circuit part which is inductively coupled to the transmission line.
