ASR423.22E-T

Overview

The ASR423.22E-T is a single-port Surface Acoustic Wave (SAW) resonator manufactured by Abracon LLC, designed for surface-mount applications. It operates at a precise center frequency of 423.22 MHz with a resonant impedance of 19 ohms. The component utilizes an 8-SMD, no-lead package measuring 5.0 x 5.0 x 1.35 mm. It supports a wide operating temperature range from -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Single-port SAW resonator architecture optimized for RF signal processing
• Industrial-grade thermal stability across extended temperature ranges
• Standardized SMD footprint facilitating direct PCB integration

Applications

• ISM band wireless remote control systems
• Industrial wireless sensor networks
• Sub-GHz low-power data transmission modules

Procurement Notes

Verify the specific ordering suffix against official Abracon documentation to ensure correct packaging configuration. Confirm that the selected variant matches the required surface-mount termination style and lead-free compliance specifications for your manufacturing process.

Selection Notes

Select this component when designing circuits requiring stable oscillation near 423 MHz within industrial temperature constraints. Ensure the RF input power remains within safe limits to prevent frequency drift. Validate impedance matching for the 19-ohm resonant characteristic in the target schematic design.

Part Context

This device belongs to the ASR series of SAW resonators, which are engineered for high-frequency timing and filtering tasks. These components serve as critical passive elements in radio frequency front-ends, providing frequency selectivity and stability without active power consumption.

Replacement Considerations

Direct substitution requires matching the 423.22 MHz center frequency, 8-SMD package dimensions, and -40°C to +85°C operating range. Verify that alternative SAW resonators offer comparable insertion loss and temperature coefficient characteristics to maintain system performance.
