Custom Delay Lines
The chart below illustrates some of the important electrical parameters of various delay lines for different applications.

          

Over the past three decades, Allen Avionics has produced custom-designed delay line designs for many applications.

There have been thousands of variations covering every type of passive delay line, including fixed, tapped and variable. Sizes range from standard to ultra-miniature.

Applications cover virtually the complete signal spectrum from sub-audio through sonar, RF, HF and VHF with a wide variety of pulse rates, pulse widths and duty cycles.

These specifications cover the ranges for which Allen Avionics can produce custom delay lines for your special applications.

We can also use our standard products and modify the electrical parameters or packaging to fit into custom applications.

Using HF and VHF Technology, Allen Avionics has manufactured delays with over 180 MHz bandwidth. Our "H", "RH" and "VHR" series delay lines have delay-to-rise time ratios of up to 250:1.
