Parfil designs twenty different coupled and transmission line RF/microwave filter types. All of the parameters needed for filter construction are computed. The program accounts for "T", cross, via and step junction effects. It also accounts for unequal phase velocities in coupled microstrip designs. Data is supplied in tabular and graphical form for either English or Metric units. The filter types are:
BAND-PASS COUPLED LINE FILTERS: Half wave - parallel coupled three coupling types Interdigital - three types of input/output coupling Combline - two types of input output coupling Hairpin - two types of input/output coupling
BAND-PASS TRANSMISSION LINE FILTERS: End coupled half wave Quarter wave shunt stub Stepped Impedance
LOW-PASS TRANSMISSION LINE FILTERS: Shunt stub series line Shunt stub series line - Elliptic Response Stepped Impedance

HIGH-PASS TRANSMISSION LINE FILTERS: Gap coupled & open stubs Quarter wave shunt stub
BAND-STOP FILTERS: Narrow-band quarter wave coupled line Wide-band quarter wave shunt stub
STRUCTURES: Microstrip Shielded Microstrip Stripline Suspended Substrate Rods Coupled through Septum Round Rods Rectangular Bar Coax (some Filters)
DRAW CAPABILITY: Creates DXF file Printed filter drawings on these Pages were created from DXF files.
CREATES NODAL ANALYSIS FILE: Creates a file for most filters for importing into ProCAP. Useful for creating diplexer designs adding other circuit elements and for Monte Carlo analysis. |
