Abstract
An approach is presented for realizing circulators in the form of GaAs monolithic microwave integrated circuits (MMICs) without using any ferrite material and external magnets. The configuration is known as an active circulator and is suitable for system applications where a fully integrable, lightweight, and small-size subsystem is required. The circuit is capable of providing 0 dB loss, and return loss and isolation of better than 16 dB and 23 dB, respectively, over an octave or higher bandwidth.<>
