Low profile high speed load pull tuner system
A load-pull test system uses controller, interface, calibration method and at least one low profile, two-probe, slide screw impedance tuner; the tuner probes share the same slabline; they are inserted anti-diametrical at fixed depth (distance from the center conductor) from both sides into the channel and move only horizontally along the slabline. The tuner does not have adjustable high precision vertical axes controlling the penetration of the probes and its low profile is optimized for on-wafer operations. The carriages holding the probes are moved at high speed along the slabline using linear electric actuators. An efficient de-embedding calibration method serves speeding up additionally the measurement procedure.
Oscillation-based systems and methods for testing RFID straps
Systems and methods are provided for testing remote frequency identification (RFID) straps. A testing system includes an amplifier electrically coupled to an inductor or inductive component. The system further includes a pair of contact points to be placed in contact with a pair of contact pads of an RFID strap. Connecting the contact points and the contact pads places the RFID strap in parallel with the inductor to define a resonant circuit. The characteristics of the resonant circuit as an oscillator depend at least in part on the capacitance and the resistance of the RFID strap. As such, the characteristics of the resonant circuit as an oscillator may be monitored to determine the capacitance and/or the resistance of the RFID strap. One or more characteristics of the RFID strap may be compared to one or more threshold values to determine whether the RFID strap is acceptable or defective.
