With today’s emphasis on superior performance in a smaller, lighter, more cost-effective package, why settle for yesterday’s chip and wire solutions? Narda Defense Technology Solutions has pioneered the development of high performance, densely packaged Integrated Microwave Assemblies and Sub-Systems in footprints previously considered unachievable.

By leveraging commonly available multi-layer board materials with unique interconnection techniques, and incorporating DSP and sophisticated monitor and control functions, our solutions are currently redefining “State of the Art.”

Including: Module and Subsystem Solutions to 40 GHz; Frequency Converters, LNA’s; BUC’s & SSPA’s, EW, Radar, Radio and SATCOM Applications and Pin Diode Switch Products.

The complexity of modern digital equipment has caused EMI/EMC susceptibility testing to become increasingly important. Many EMC standards have been created including MILSTD- 461, IEC 61000, ISO 11451 Automotive, EN 50, and FCC part 15 that provide specific guidelines for EMC and EMI test methodologies. Early standards required a CW carrier, or single tone with constant modulation as the disturbance test signal. This article will discuss how a peak power sensor can replace an average diode detector in a field probe to measure pulse power, improve repeatability and increase dynamic range of the power measurement.

This paper provides a comprehensive review of modern automated load-pull, including a discussion of early impedance synthesis methods, and how they were improved with breakthrough innovations such as Focus MPTTM technology and systematic high-VBW sub-1 Ω test-fixture design techniques. More recent developments are next treated, including active-loop and active-injection impedance synthesis architectures, time-domain data acquisition, and advanced data processing and visualization.

A system that utilizes OFDM/OFDMA, such as the E-UTRA (LTE) downlink or the IEEE 802.11a/g and the IEEE 802.16 physical layers, transmits OFDM symbols, each comprising a number of modulated sub-carriers carrying data or pilot symbols, with inter-subcarrier spacing being equal to or an integer multiple of a fixed frequency. The channel bandwidth (B) is determined by the number of 'occupied' (modulated) subcarriers and the subcarrier spacing.

There is a wide variety of coaxial connectors and cables available for use in the RF and Microwave spectrum. While often not much thought is given to these essential components, a misstep here can result in undesirable system degradation. Given that typical RF systems are comprised of any number of items, e.g. RF generators, amplifiers, attenuators, power meters, couplers, antennas, etc., it is not uncommon that a great deal of thought is given to these “high end devices while mundane items such as connectors and cables are often treated as an afterthought".

Whenever time to market is critical, rapid prototyping can produce a first draft of a new product that allows testing, evaluation, and further refinement of the product idea, which helps a company more quickly and cost-effectively transform early concepts into marketable products. At the same time, for concepts that may not make practical products, rapid prototyping can spare a company further investment time and expenses by revealing the product's flaws at an early stage of the development process.

The Anritsu VectorStars Noise Figure Option 041 enables the capability to measure noise figure (NF), which is the degradation of the signal-to-noise ratio caused by components in a signal chain. The NF measurement is based on a cold source technique for improved accuracy. Various levels of match and fixture correction are available for additional enhancement. VectorStar is the only VNA platform offering a Noise Figure option enabling NF measurements from 70 kHz to 125 GHz. It is also the only VNA platform available with an optimized noise receiver for measurements from 30 to 125 GHz.
