In this paper, five topologies of microwave active filters (MAFs) are studied. We have considered MAFs proposed earlier in the class of filters with compensation for loss. First we have investigated theoretically the noise properties of various approaches to compensate for losses in microwave resonators. Then five third order microstrip active filters were simulated to validate a choice of the best configuration. It was shown that the use of negative resistance with minimized noise measure… CONTINUE READING
