The new generation of AWGs can address a broad range of applications and test cases. This primer discusses characteristics and fundamentals of an arbitrary waveform generator and the different implementations available in the market.
Because coaxial cable assemblies are so vital to such a wide range of
systems, from rugged ground-based electronic systems to orbiting satellites in space, the selection process
for those cables should not be treated lightly. Choosing the right coaxial cable assembly is not a trivial task,
but it is one that can be made somewhat easier by better knowing what to look for in a high-frequency or
high-speed coaxial cable assembly.
This application note looks at VCO fundamentals, for typical oscillator designs through tuning sensitivity characteristics. Examples of a Colpitts and Clapp circuit are presented.
Testing at millimeter-wave frequencies brings new and different measurement challenges, so minimizing measurement uncertainty is critical in the development of these new technologies. This white paper discusses the challenges associated with millimeter-wave testing and how to optimize your Vector Network Analyzer (VNA) measurement capability to provide the confidence required to make performance/cost tradeoffs.
Dual-polarity supplies are commonly needed to operate
electronics such as op amps, drivers, or sensors,
but there is rarely a dual-polarity supply available at
the point of load. The LTCî3260 is an inverting charge
pump (inductorless) DC/DC converter with dual low
noise LDO regulators that can produce positive and
negative supplies from a single wide input (4.5V to
32V) power source. It can switch between high efficiency
Burst Modeî operation and low noise constant
frequency mode, making it attractive for both portable
and noise-sensitive applications.
Commonly used substrates for high power resistors and terminations are Beryllia, Aluminum Nitride, and to alesser extent, Boron Nitride and Silicon Carbide. While these materials are known for their superior thermal properties, none of them come even close to matching the thermal conductivity of CVD Diamond.
The Mini-Circuits family of microwave monolithic integrated circuit (MMIC) Darlington amplifiers offers the RF designer multi-stage performance in packages that look like a discrete transistor.
Learn more about the background of radar systems and the role of transponders in these systems, and why periodic maintenance and calibration of transponder test sets are important for ensuring aviation safety. This application note provides examples of how to effectively test transponders to validate their performance and function, covering topics such as interrogation and reply transmit power and pulse profiling, double pulse spacing, and reply delay timing measurement.
Fiber Optic Delay Line systems (FODL) are used in test and
development laboratories to eliminate outdoor range testing
of radio and radar systems. Outdoor range testing is
costly, complex, and time-consuming.
The True Balanced/Differential technique uses two sources to create actual differential and common-mode stimuli, hence the shortened name true-balanceÂ. This white paper offers guidance to signal integrity designers on the differences between these approaches and which one may best fit their need.
