Both the Circulator 3rd port and Termination/Attenuator are specified to meet a VSWR over a given frequency band. The actual isolation result will depend on the phase of the Return Losses. An optimal...

Conventional LTCC material systems offer three standard metallization schemes, silver, gold and a mixed metal. For high reliability projects, the gold system is a common choice. When price is a...

Terminations designed to dissipate significant amounts of power at RF frequencies have traditionally been fabricated on beryllium oxide (BeO) substrates. The high thermal conductivity and moderate...

Barry Industries offers parts using flanges made from both copper tungsten (CuW) and copper (Cu) flange materials. In the case of the copper tungsten flange material the construction is 100% brazed....

The finite element analysis described in this report was performed to support the conclusions of the Barry Industries' report "Materials Selection for High-Power / High Reliability Resistors", Jack...

Surface mount (SMD) resistors are often employed in microstrip circuitry at RF frequencies. Typical SMD resistors designed for general purpose circuitry are usually trimmed using plunge trim or "L"...

The RF and microwave characteristics commonly used to define the performance of components are typically measured using a vector network analyzer. Since the packages of devices manufactured by Barry...

The ability of a surface mount resistor to dissipate a given amount of power is ultimately limited by the temperature of the active resistor film. Assuming that the effects of convection and radiation...

Barry Industries products with a "CT" metallization scheme are widely used in customer applications that require solder mounting. This application note addresses the requirements for soldering to...
