TL Series

Tubular Lowpass Filters

 

    Tubular Lowpass Filters are used to suppress harmonics and high
 frequency interference.Typical applications include low to medium power 
 transmitter output filters and test equipment receiver inputs to improve 
signal quality.
    Each Lowpass Filter is a precision machined captivated assembly. 
 Integrated high and  low impedance elements within the assembly allow for
 excellent electrical performance with the smallest possible package size.
    High/Low Impedance Lowpass Filters have many desirable traits
 when  compared to other construction styles. Manipulating the characteristic
 impedance  of a transmission line yields an inherently low-profile, axially
 connected filter with a minimal number of solder  joints. The net result
 is high performance and reliability at a low per piece cost.
Features....
  • In-Line, low profile construction
  • Temperature stable
  • Custom units available
  • High power units available
  • Broad range of cutoff frequencies and rejection specifications
  • Multiple connector and mounting options
  • Low VSWR
