The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.
This application note introduces IQ, single sideband (SSB), and image reject (IR) mixers in both theory and practice. We will discuss basic applications, their concepts, and practical considerations in their selection and use.
Baluns have long been ubiquitous in low frequency audio, video, and antenna driving applications. The need for high speed, low noise data transfer has driven the advancement of the balun to higher frequencies and superior performance.
This white paper explores Marki Microwave's key metrics for modern competitive filter technology achieved through GaAs MMIC process. It showcases the capabilities of MMIC filters and a companion design tool, enabling fast and accurate development without excessive resource consumption.
