In today's competitive environment designers and engineers are looking for any features that can give them the edge. When it comes to RF connectors, areas where that advantage can be gained are in the speed of installation, flexibility of connection and efficient utilization of space. The QuickLock family of...

Lockheed Martin has received a contract for $341 M from the US Army Aviation and Missile Command (AMCOM) for the production of the Patriot Advanced Capability (PAC-3) Missile. Under the contract, Lockheed Martin Missile and Fire Control will produce 88 PAC-3 missiles plus other associated hardware. Production of all...

The Accu-Test™ products are a family of precision cable assemblies that are designed for use in the DC to 40 GHz frequency range, intended to facilitate accurate measurements and exhibit low loss characteristics at a competitive price for precision test and measurement applications. The family is currently comprised of...

When developing and producing complex RF connector housings, costs can be high and the process complex due to the sheer number of required machined metal components and the diversity of the necessary assembly. However, these difficulties can be overcome by employing molded injected metal (MIM) technology for connector manufacturing....

With all the talk about a wireless society, there is still a need for high performance coaxial cable assemblies. One of the areas still getting lots of development attention is cable assemblies for airborne electronic warfare. Most of these applications are at power levels too high for fiber optic...

Accurate, nonlinear, active device models are critical to achieving design success for circuits such as power amplifiers, oscillators and mixers, using computer-aided engineering (CAE) software such as Agilent Technologies' Advanced Design System (ADS™), Applied Wave Research's Microwave Office™, Eagleware's Genesys™ or Ansoft's Serenade™. Prior work has made it clear...

The rapidly increasing use of differential RF and microwave circuits has created many new measurement challenges. In S-parameter measurements, for example, transmission phase accuracy could often be ignored with little impact on specification-critical measurements. This is no longer true in the measurement of differential circuits, since seemingly small phase...

Traditional capacitor and inductor models have consisted of two or three elements (capacitor examples are shown in Figure 1 ). The two-element models provide a simple way to define the device. From a circuit designer's viewpoint, the two-element models may suffice for applications where the component is being used...

As this article is written, it is estimated that 90 to 98 percent of first-level IC interconnects are made using wire bonding technologies. The remaining connections are primarily bump, or flip-chip connections. This ratio is expected to remain the same for the foreseeable future. In general, it will be...

In a contract worth approximately US$3 M, AMS, an equal shares joint venture between Finmeccanica of Italy and BAE Systems of the UK, has signed a contract with the Civil Aviation Authority of China (CAAC) to supply two mono-pulse versions of SIR-S, the AMS Mode-S Secondary Radar, to be...
