Abstract (en)
A dual-band non-reversible circuit device is constituted by two circulator components operating in different frequencies in a magnetic circuit. One circulator component is a lumped constant type component operating toward the low frequency side. The other circulator component is a distributed constant type component operating toward the high frequency side. <IMAGE>
