The DR3000-1 is a Surface Acoustic Wave (SAW) resonator manufactured by RF Monolithics, Inc (now Murata Electronics). SAW resonators are passive electronic components used in radio frequency (RF) applications for frequency control and filtering. The DR3000-1 is designed to operate at a specific frequency, providing stable and accurate frequency reference in various wireless communication systems.

Applications:

• Remote Keyless Entry (RKE) Systems
• Wireless Sensor Networks (WSN)
• Garage Door Openers
• Security Systems
• Low-Power Transmitters and Receivers

Features:

• SAW Resonator: Provides stable and accurate frequency control.
• Fundamental Mode Operation: Operates at its fundamental resonant frequency.
• Low Insertion Loss: Minimizes signal attenuation.
• High Q-Factor: Provides sharp frequency selectivity.
• Small Footprint: Suitable for compact wireless devices.

Benefits:

• Stable Frequency: Ensures reliable operation of wireless systems.
• Low Power Consumption: Extends battery life in portable devices.
• Simple Implementation: Easy to integrate into RF circuits.
• High Performance: Provides excellent frequency selectivity and stability.

Additional Details:

The DR3000-1 operates based on the piezoelectric effect, where mechanical vibrations are converted into electrical signals. The SAW resonator is fabricated on a piezoelectric substrate, with interdigital transducers (IDTs) used to excite and detect acoustic waves. The resonant frequency is determined by the physical characteristics of the substrate and the IDT pattern. The DR3000-1 is typically used in oscillator circuits to provide a stable frequency reference. It can also be used as a filter to selectively pass or reject signals at specific frequencies. The low insertion loss and high Q-factor of the DR3000-1 ensure efficient and reliable operation. Due to RF Monolithics Inc. being acquired by Murata, newer designs may utilize a direct Murata equivalent SAW resonator. Datasheets and application notes are available from Murata, providing detailed information about its operation and usage.
