Abstract
The error vector magnitude (EVM), used generally to quantify digital communication performances, will be used in this paper in order to test RF device performances. This RF test particularly developed for industries will respond to time and cost-reduction requirements. The method is based on the simplest digital modulation, quadrature phase-shift keying modulation on an RF carrier frequency. Primary results based on this method have been obtained using Butterworth and Chebyshev RF filters. In this work we improve the sensitivity of the EVM parameter to filter characteristics as the center frequency, the bandwidth, the insertions losses, and the ripples in the passband. Simulations with ADS Ptolemy and measurements are done for both filter types with the aim of defining their EVM signatures in the passband.
