Product Specifications

Technical details and manufacturing context for Delay line

Definition

A delay line is a critical component within a timing generator that creates a controlled time delay for electrical signals, enabling precise synchronization, signal alignment, and timing adjustments in electronic circuits and systems. It is used in applications such as radar, communications, and test equipment where signal timing is essential. The delay line operates by propagating an electrical signal through a physical medium—such as a length of coaxial cable, a surface acoustic wave (SAW) device, or a digital memory buffer—where the signal's travel time through the medium creates the desired delay. The delay is determined by the physical length and propagation velocity of the medium or by digital clock cycles in electronic implementations. This product is available with a range of specifications that must be verified for the specific model and application. Key parameters include a delay time range of 1–1000 ns, with a tolerance of ±0.5 ns; insertion loss of ≤1.5 dB at center frequency; impedance of 50 Ω (75 Ω optional); frequency range of 0–3 GHz (upper limit depends on model); return loss of ≥18 dB over operating band; operating temperature of -40–85 °C (storage -55–125 °C); rated voltage of 50 V DC; rise time of ≤1 ns (10%–90% of step); temperature coefficient of ≤50 ppm/°C; typical dimensions of 10×5×3 mm (SMT package, varies by model); and weight of ≤2 g (approximate). Materials used include copper, dielectric insulator, and semiconductor substrate. These values are reference ranges and must be confirmed with the legal manufacturer or supplier for the intended use. Always verify model-specific values and standards before procurement.

Working Principle

The delay line introduces a controlled time delay by propagating an electrical signal through a medium with a known propagation velocity. In analog implementations, the signal travels through a length of coaxial cable or a SAW device, where the physical length and the velocity of propagation determine the delay. In digital implementations, the signal is stored in a memory buffer and read out after a set number of clock cycles. The delay time is set by the design and can be selected per model, with custom ranges available. The device's performance is characterized by parameters such as insertion loss, return loss, and temperature coefficient, which affect signal integrity over the operating range.
