In one embodiment of the present invention there is provided a filter having a first spiral support member having a first end and a second end, a second spiral support member positioned adjacent the first spiral support member to form an open loop between the first end and the second end of the first spiral support member; and a filtering structure attached to the open loop. The apparatus comprises laser cutting means, means for de-laminating the self-adhesive label web from the carrier sheet and directing the label web past the laser cutting means to cut a label out of the label web, and means for re-laminating the cut label web to a carrier sheet. Generally, the local oscillator frequency associated with the sideband having a lower energy is selected.
