New Patent: High Speed Hybrid Active Load Pull

ABSTRACT A high speed tuning and measuring algorithm is used for production level testing on-wafer a large number of chips. It applies to a hybrid active injection load pull test system. Using a pre-calibration of the passive tuner and the amplitude and phase settings of the active power injection signal

New Patent: High Power Slide Screw Tuners

ABSTRACT Impedance tuners used in high power measurements suffer fast heating and consequently thermal expansion of the center conductor, which has a very small mass and is thermally isolated from the environment and tuner housing. This leads to false measurements or catastrophic tuner failure (short) of either the DUT or

New Patent: Method for Calibration and Tuning with Impedance Tuners

ABSTRACT An impedance synthesis method for single and multi-probe high resolution slide screw impedance RF and microwave tuners employs a fast calibration algorithm, which creates appropriately distributed calibration points over the Smith chart and a second order interpolation algorithm between calibration points, optimized for best suitability to the natural behavior

New Patent: Compact Two Probe Impedance Tuner

ABSTRACT An automated “double-decker” slide screw impedance tuner uses two tuning probes, independently movable inside two stacked circular slablines, which lie flat on the bench table. The eccentrically self-rotating disc probes are mounted at the end of rotating radial arm-carriages, the total mechanism operating in a planetary configuration. The radial

New Patent: Multi-band Low Frequency Impedance Tuner

ABSTRACT A multi-band, electro-mechanical programmable impedance tuner for the frequency range between 10 and 200 MHz uses cascades of three or more continuously variable mechanical capacitors interconnected with sets of low loss flexible or semi-rigid cables; for each frequency band a different set of cables and capacitors are used. The

New Patent: Coaxial Alignment Instrument Adapter

ABSTRACT An adapter alignment device, that can be added on the coaxial RF connectors of instruments,   especially slide screw impedance tuners, aligns and guides precisely and repeat ably the male and female adapters into each-other. This leaves the internal center conductors of the tuner slabline,   which are attached to the

New Patent: Noise Parameter Measurement System

ABSTRACT A noise parameter test setup allows accurately measuring the four noise parameters (Fmin, Rn, Γopt) of microwave transistors over a wide frequency range using two wide-band directional couplers, instead of SPDT switches, to merge the s-parameter (signal) measurement path and the noise measurement path, avoiding thus the uncertainty of
