Microwave Bulk Acoustic Wave (BAW) Delay Lines | 300MHz-18GHz | Custom OEM/ODM

Product Overview

Our Bulk Acoustic Wave (BAW) delay line series offers high-reliability acoustic delay solutions for demanding RF and microwave applications. Using sapphire or quartz crystals as the delay medium and sputtered ZnO thin-film transducers, these devices convert electromagnetic energy into acoustic energy, providing a highly stable, non-dispersive time delay.

Why Choose Our BAW Delay Lines?

Non-Dispersive: Time delay remains constant across the operating bandwidth.

Ultra-Wide Frequency Range: From 300 MHz up to 18 GHz.

Long Delay in Compact Size: Acoustic velocity is >10,000 times slower than free space, enabling up to 30 µs delay in a compact package.

Two Configurations:

Two-Port (Transmission): Simplest type for standard delay requirements.

One-Port (Reflection): Ideal for radar self-test and calibration, providing multiple echoes (0, 1, 2, 3... times the basic delay).

High Stability: Sapphire crystals offer
