Tubular Lowpass Filters

    18162    18228

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. The tubular design integrates high and low impedance elements within the assembly resulting in excellent electricial performance in the smallest possible configuration.

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.
