    Abstract: An exhaustive review of millimeter-wave (mm-wave) active bandpass filters (BPFs) is presented in this article. The details of various design approaches and realization techniques for the implementation of active BPFs are provided. The strengths, weaknesses, and design challenges of active BPFs are discussed. The available process technologies are investigated for the development of mm-wave filters. Active BPFs exhibit the merits of low loss, good outof- band rejection, good selectivity, and a high integration level. By applying loss compensation techniques, active BPFs are realized with low losses. The aim of this paper is to motivate research and development of high performance mm-wave BPFs, especially above the 60 GHz frequency band.
