Abstract: In a testing circuit performing a testing operation to detect an RF circuit characteristic, a first filter unit is provided, having a first external terminal electrically coupled to a testing signal and a second external terminal electrically coupled to an RF circuit of the RF device. The first filter unit is configured to allow the testing signal to enter the RF circuit while blocking an RF signal transmitted in the RF circuit from entering the testing circuit. In addition, a testing-result informing unit is provided, having an external input electrically coupled to the first external terminal, and generating an informing signal, which indicates a condition of the RF circuit according to an electric level at the external input.

Abstract: An impedance matching structure is disposed on a multilayer circuit board for matching an impedance of a transmission line for transmitting an electronic signal. At least one redundant conducting section is coupled to a conductive member of the transmission line between input and output terminals of the transmission line. The conductive member and the redundant conducting section are disposed in a corresponding plating hole. At least one grounding member disposed adjacent to but separated from either or both of the conductive member of the transmission line and the at least one redundant conducting section in a capacitor structure for impedance matching. The at least one grounding member includes a first grounding member penetrating through at least two layers of the multilayer circuit board.

Abstract: In an intelligent monitoring system, a wireless signal processing device transmits a wireless signal toward a first target object in a monitored area, receives a wireless status signal, and generates a monitoring signal corresponding to the first target object according to the wireless status signal. In addition, at least one signal-relaying device receives a back scattering signal, which is reflected from the first target object in response to the wireless signal, transfers the back scattering signal into the wireless status signal, and transmits the wireless status signal to the wireless signal processing device. The signal-relaying device includes a power supply device for supplying power for operations of the signal-relaying device, and the signal-relaying device is disposed in the monitored area between the first target object and the wireless signal processing device.
