A Broadband Tunable Band‐Pass Filter for RF Characterization Within TETRA and LTE Bands

Abstract

This article presents a broadband tunable band‐pass filter which operates between 380 and 960 MHz covering the trans‐European trunked radio, AMPS, GSM900, and long‐term evolution “whitespace” bands. The design has an increased operational tuning range when compared to existing designs and is suitable for low‐cost wireless spectrum bandwidth expansion analysis and spectral efficiency analysis. © 2013 Wiley Periodicals, Inc.
