摘要：
In this paper, the use of 'Composite Right/Left Handed' (CRLH) devices in a first-order recursive active filter topology is proposed. The intention of the design with these CRLH devices is to obtain a circuit with a dual-band filtering behaviour at two arbitrary frequencies. Dual-band CRLH branch-lines in the input and output ports allow obtaining well input/output matching. On the other hand, a CRLH feedback transmission line is used to compensate the phase of the amplifier at the two operating filter frequencies.
