A device under test is connected between said third port and a third port of a second duplexer. Each of the first and second ports of the second duplexer is connected to a PIM optimized load and/or a standard load. The second duplexer is preferably identical to the first duplexer. For minimizing self-intermodulation, at least the first duplexer comprises at least one filter component and a metal housing.

摘要： Embodiments of the present disclosure use customizable waveguides that can be positioned next to each other in a structure that contains one single flange to provide a physical connection for the waveguides. In this fashion, many waveguides can be positioned within a small area to accommodate a tightly packed patch antenna array so that the waveguides can be positioned very close to the socket. As such, embodiments of the present disclosure allow more waveguides to be packed into a small area by providing a single structure that houses many waveguides and share only a single flange connection element that can be sized appropriately.

摘要： An apparatus for sensing RF current delivered to a plasma includes an RF conductor along which the current is delivered to the plasma and which is divided into two parts along part of its length so that substantially equal currents flow in each part. A sensor device is inserted into the gap between the two parts of the conductor and includes first and second inductive loops disposed one n each side of the gap such that when an RF current flows along the RF conductor t magnetic flux surrounding the conductor which is generated by the RF current couples with the loops respectively in opposite directions relative to the sensor device. If a stray magnetic flux normal to the current direction couples with the loops in the same direction relative to the sensor device it will induce voltages in the loops which respectively add to the voltage induced by the RF current in one loop and subtract from the voltage induced by the RF current in the other loop. Thus by adding the voltages induced in the loops, for example by connecting them in series, the voltages induced by the stray magnetic flux tend to cancel.

摘要： A system and method for testing wireless communication devices uses a waveguide designed for operation beyond cutoff for frequencies used by the wireless communication device to be tested. The waveguide has first and second ends with at least an opened first end to permit the easy insertion and removal of the wireless communication device. An antenna located within the waveguide and coupled to an external test system permits wireless communication between the external test system and the wireless communication device when inserted in the waveguide. Radio frequency (RF) signals propagate between the antenna located within the waveguide and the wireless communication device when inserted into the waveguide. The length of the waveguide is designed to provide sufficient attenuation of RF transmissions when measured at the opened end of the waveguide. The opened end of the waveguide advantageously permits the easy insertion and extraction of a wireless communication device while the waveguide dimensions prevent the leakage of RF signals into and out of the waveguide. The external test equipment includes a transmitter and receiver that are designed to operate at frequencies used by the wireless communication device. The system may be used to collect data to analyze the wireless communication device or to collect transmission characteristics to be used to establish a fingerprint for subsequent identification of the wireless communication device. The external test system may operate under control of a processor or a central computer system. Data collected by the external test system may be analyzed by the processor or the central computer system.

摘要： An RF sensor having a novel current sensing probe and a voltage sensing probe to measure voltage and current. The current sensor is disposed in a transmission line to link all of the flux generated by the flowing current in order to obtain an accurate measurement. The voltage sensor is a flat plate which operates as a capacitive plate to sense voltage on a center conductor of the transmission line, in which the measured voltage is obtained across a resistance leg of a R-C differentiator circuit formed by the characteristic impedance of a connecting transmission line and a capacitance of the plate, which is positioned proximal to the center conductor.
