This document provides step-by-step instructions on using the Rigol DSA-800 series of Spectrum Analyzers to measure the characteristics of an RF Bandpass filter. The DSA must have a Tracking Generator ...

This paper presents the design and performance of a key RF circuit necessary for the realization of a reconfigurable, integrated RF front-end: a tunable frequency, selectable bandwidth, on-chip, ...

Balun bandpass filters represent a critical advancement in radio frequency (RF) circuit design, integrating the dual functions of balanced-to-unbalanced conversion and frequency selection. These ...

Integration in the radio-frequency (RF) front end of Global System for Mobile Communications (GSM) mobile handsets is continuing to advance through the use of modules, from front-end modules (FEMs) to ...

Software-defined radios are great tools for the amateur radio operator, allowing visualization of large swaths of spectrum and letting hams quickly home in on faint signals with the click of a mouse.
