| HELICAL FILTERS Specimen Specification 815MHz HELICAL FILTER Part: TT67214A-815M DESCRIPTION Helical filters offer a variety of benefits in comparison with SAW filters including customer specification of centre frequency and bandwidth, no initial design charges, lower insertion losses and lower impedance. In addition, the simpler design of helical filters enables smaller quantities to be produced economically and with quicker delivery.
