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 LTCÃÂ®3260 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 ModeÃÂ® 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.
