This paper reports results of investigations on edge guided mode circulators and junction circulators using thick film ferrimagnetic pastes in the frequency range from 2 to 12 GHz. Performance of the circulators realized with the thick film ferrimagnetic pastes will be compared with those made on YIG substrates in respect of insertion loss, isolation and bandwidth. The study shows that while good isolation bandwidth is obtainable with edge guided mode circulators, the insertion loss remains high.
