摘要： Methods and systems are disclosed which allow testing essential performance parameters of broadband communications systems, while using test channels of lower bandwidth, allowing thus lower cost hardware (or use of legacy test system). In particular, the methods and systems allow testing of EVM in digital systems, especially OFDM systems. The methods and systems readily apply to test equipment for production lines, such as IC testers of final product testers.

摘要： In some applications network parameters vary over time in a manner that precludes the use of conventional swept frequency network analyzers. Swept measurements incur penalty both in terms of acquisition time, and in terms of registration between measurements taken at the beginning and at the end of a sweep. Disclosed is an architecture and method for real-time analysis of network parameters. Example applications are presented, ranging from thermal drift of amplifiers, to microwave imaging of moving objects, to characterizing materials on conveyors, to characterizing plasma buildup, and many more.

摘要： A microwave imaging sensor is disclosed for continuously monitoring the condition and status of an in situ reverse osmosis membrane that forms a semi-permeable barrier between a region of water containing a dissolved salt and a region of water which is intended to be substantially free of the dissolved salt. A device according to embodiments of the invention can be used to monitor the condition of the membrane, i.e., the ability of the membrane to filter water by reverse osmosis; and to detect failures in the membrane such as leaking saline water into the output stream. The results of the monitoring can be used to determine in real time whether or not the membrane should be replaced.

摘要： A microwave imaging sensor is disclosed which is resilient to background and skin clutter. Resilience is obtained by cancellation of skin reflections without mechanical displacement of the microwave antenna array or the subject, by utilizing reflections from other antennas and compensating for differences in propagation. The cancellation takes into consideration the expected strength of the reflection at different points in time and for different pairs, in order to minimize the effects on the image, and particularly on image reconstruction of symmetric targets.

摘要： A method and apparatus for enhanced microwave imaging of an object collects microwave responses for multiple combinations of transmit antennas, receive antennas, and object movement states. The responses are grouped into sets of responses corresponding to at least two object movement states. An image is reconstructed from the set of responses for each movement state, and a differential image representative of object movement is generated from the reconstructed image for each of the at least two object movement states. The differential image is overlaid on a reconstructed image to obtain an enhanced composite image of the object.

摘要： A tapped transmission line for distributing an electrical signal, such as an RF signal, to multiple modules, and/or aggregating signals from multiple modules. Embodiments of the invention provide a tapped transmission line based on a transmission-line medium along which tap elements are dispersed, so that the tap elements have a predominantly capacitive loading of the transmission-line medium. Methods for compensating the loss of the transmission-line medium are presented as well. Applications for distribution of transmitted signals, of local oscillator signals, and to aggregation of signals from multiple oscillators are disclosed. The invention is particularly applicable to integrated circuits (IC, ASIC, RFIC), and to multichannel RF systems such as phased array and MIMO systems.
