Abstract

This paper presents a three stage all-pass network (APN) designed as a novel semi-lumped configuration to achieve a wideband group delay response with a linear negative slope. Semi-lumped APN design reduces the total number of surface mount components, thereby enhancing the ease of production and repeatability of results. A high group delay dispersion of -2.25 ns/GHz is achieved with a fractional bandwidth of more than 40 % in a frequency band of 2 - 4] GHz. Insertion loss is less than 2.4 dB with a return loss better than 12 dB over the bandwidth.
