APITech's Delay Lines

Delay lines are essential for applications that need a calculated time delay in signal transmission. At APITech, we provide a range of delay lines designed for applications that need high performance and reliability. Our strong heritage in manufacturing makes us a trusted provider for military and other mission-critical applications.

High-performance delay lines are offered in various topologies, covering a wide range of specifications. Whether you are looking for a passive or active delay line, we provide either semi-standard or custom delay lines that are configured to meet your requirements. We specialize in SAW delay lines, which are available in packaging options such as ceramic leadless chip carriers suited for harsh applications.

We also offer many interface options, including SMA (Female and Male), N-Type (Female), TNC (Female), Leaded and SMD interfaces. Our delay lines also are available in multiple small package sizes, delay requirements, and temperature compensation. APITech’s delay lines are ideal for use in signal processing circuits, radar systems, communications, electronic warfare, and other applications that require channel equalization and calibration.
