["The TBCP3-1000 is a fixed aperture RF current monitoring sensor. It has a very flat response with a 3dB bandwidth of 1 GHz and is characterized and usable over the frequency range from 30kHz to 1 GHz. The aperture of the HF current measuring probe is 17 mm. Their transmission impedance is in the range from 3 MHz to 1 GHz, close to 20 dB Ohm. Tekbox supplies a calibration device that corresponds to the TBCP3 series of fixed aperture current sensors", "Characteristic frequency range: 30 kHz to 1 GHz", "Opening diameter: 17 mm", "External diameter: 52 mm", "Height: approx. 14 mm", "Weight: 55g", "Connector type: SMA female", "Transmission impedance: 20dBΩ", "Primary current (DC - 400 Hz): 30 A", "Maximum Primary Current (RF): 4A", "Max. core temperature: 125 °C"]
