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.
