Claim:
1. A conducted type current probe, comprising: a plurality of first resistors connected in parallel to form a resistor with 1Ω resistance value; at least one second resistor including 49Ω resistance value and connected in series with the first resistors to reduce parasitic impedance in an equivalent circuit of the first resistors and enhance the power capability of the current probe; a first connective port connected with a test point of a test integrated circuit (IC); and a second connective port connected with a test receiver by a coaxial cable; wherein the first resistors and the second resistor are electrically connected by a coplanar-waveguide (CPW) transmission line, and the conduced type current probe is implemented in a 1Ω/150Ω direct coupling method to analyze an RF currents/voltages.
