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