摘要：

In this paper we present several topologies of simple non-reflective filters using transmission fines and resistive elements. These filters are well-matched at all frequencies, making them especially suitable for gain slope equalizers without the need for external attenuators or isolators. The application of these filters to a 24 GHz, +/- 15 dB selectable-slope equalizer for the Expanded Very Large Array is described with measured results that are in good agreement with theory.
