title: Modular two-dimensional analysis of SAW filters. II. Analysis and compensation results.
abstract: For pt.I see ibid vol.39, no.1, pp.61-72 (1992). Physical effects causing distortions of the transfer function of a broadband (36% fractional bandwidth) spectrum shaping filter for digital radio with 16 quadrature amplitude modulation (QAM) are analyzed separately and connected with the modular two-dimensional (2-D) model described in Part I, demonstrating the importance of every single effect. A compensation of the second-order effects is performed, yielding an agreement between simulation and measurement in amplitude and phase of more than +/-0.1 dB and +/-1 degrees all over the passband. The stopband is also predicted with high accuracy.
