Understanding Ceramic Coaxial Resonator Filters

Ceramic resonator filters boast impressive Q-factor and relative permittivity, allowing a unique combination of low passband insertion loss with minimal ripple, very steep roll-off and deep rejection floor on the order of 80 to 100 dB, all in a small, surface-mountable device. They’re ideal solutions for many sensitive applications in crowded spectral environments where size is a critical requirement. Read on to learn more about the characteristics and advantages of these useful filters as well as Mini-Circuits’ industry-leading design and manufacturing capabilities.

Understanding Suspended Substrate Stripline Filters

Suspended substrate stripline filter technology offers many advantages for designers looking for wide passbands, deep rejection and sharp roll-off in the transition. By utilizing air cavities instead of dielectric materials used in traditional stripline fabrications, these filters achieve better Q and better thermal stability, making them suitable for many high-performance applications in a wide range of operating conditions. This practical overview explains everything you need to know about Mini-Circuits’ line of suspended substrate filters and multiplexers.

Navigating Amplifier Thermal Analysis

Most Mini-Circuits connectorized amplifiers are offered with and without heat sinks to give customers the freedom to design their own custom heat sink if desired. Amplifier thermal characteristics are provided on every datasheet, but there’s more than one way to go about thermal analysis depending on what information is explicitly specified. This app note reviews the basic calculations you’ll need to navigate the process for any amplifier model in our portfolio!

RF/Microwave Equalizers: An Essential Ingredient for the Modern System Designer

Gain flatness specifications have become more demanding for receiver and transmitter operating across wider bandwidths as modern military, satellite and wireless communications systems evolve. Gain a better understanding of how fixed equalizers are an essential element in wideband system designs, as well as their effects on other system parameters like noise figure, IP3 and P1dB.

Test Equipment that Adapts to Your Changing Needs

Modular test systems give you the ability to configure hardware for your unique needs with fast turnaround times and lower cost than a custom design. But what happens when your needs change? Mini-Circuits ZTM-series modular test systems make it easy to reconfigure your hardware as needed at minimal cost and without replacing the whole system. See how our modular solution helped one communications equipment manufacturer save time and effort in their current and future test setups.

A Quick Guide to Mixer Topologies

Mini-Circuits offers hundreds of mixer models representing six different circuit topologies. While this variety gives designers options for just about every application, it can also complicate the component selection process. This quick guide provides a comparison of the different mixer topologies to help you decide which one is right for your requirements.
