Generally speaking microwave and RF connectors tend to be viewed as simple, uncomplicated components. What is often overlooked, however, is that there are special applications requiring special connectors that have specific properties and characteristics. A prime example is Radiall’s range of non-magnetic RF coaxial connectors that have applications primarily...

We are very pleased to offer this updated survey of companies providing connectors, cables and cable assemblies. Sixty-seven companies responded to our request for information this year, which is an increase from the 56 companies in last year’s survey. Many of last year’s participants have updated their information as...

With today’s emphasis on small size and light weight, the coaxial RF connector is rapidly becoming one of the larger components in a modern electronic system. To help counter that trend, AEP has introduced a new microminiature SMP connector series that combines high performance and high frequency capability with...

Recognition that the key requirements of test equipment used in an automated production environment are high throughput and reproducibility has led to the development of the R&S SMATE 200A vector signal generator. Designed as an optimum solution, this instrument features short setting times for frequency and level changes plus...

With 30 years of experience as a supplier of space-qualified components and subsystems, COM DEV is well familiar with the challenges faced by the space industry in testing low volume, high performance, high reliability components. Thorough testing under difficult test conditions is required at each step of the production...

Typical established satellite transponders are often configured with channel bandwidths of between 26 and 72 MHz depending on the satellite system, although bandwidths between 5 and 120 MHz are not uncommon. This bandwidth was considered to be more than acceptable when the satellites were launched, but with the increasing...

In 2003 Focus Microwaves introduced its iTuner computer-controlled electro-mechanical microwave tuner product line. At the time it featured a frequency range of 0.2 to 18 GHz, and was completely self-contained and fully calibrated as a result of the powerful internally housed micro-controller. This innovative new device revolutionized production testing...

A library of robust models featuring substrate scalability and temperature dependence is now available for surface-mount diodes. The Modelithics Nonlinear Diode (NLD™) Library contains a compilation of measurement validated nonlinear diode models developed from I-V, C-V, small- and large-signal S-parameter characterization data. Over-temperature testing, combined with Modelithics’ patent-pending substrate-scalability...

I first realized there was a major problem in 1982 when I moved from GE Valley Forge Space Division to GE Electronics Laboratory (E-Lab) in Syracuse to design some of the first GaAs monolithic microwave integrated circuits (MMIC). I took over the design of a C-band low noise amplifier...

Because of the rapid growth in density and complexity of modern integrated circuit interconnects, modeling has been a requirement in circuit design and simulations. On-chip interconnects have achieved a dominant role, especially in determining the performance of RF and monolitic microwave integrated circuits (MMIC). In the last two decades,...
