ADUD-R-0004

RF Multiplexers Overview

The ADUD-R-0004 is a Surface Acoustic Wave (SAW) duplexer manufactured by Abracon LLC. It operates within two distinct frequency bands: 746 MHz to 756 MHz and 777 MHz to 787 MHz. The component utilizes a compact surface-mount package measuring 1.80 mm x 1.40 mm x 0.50 mm. It provides typical isolation ranging from 60 dB to 63 dB and supports a maximum voltage rating of ±5 VDC. Designed for low insertion loss and minimal ripple deviation, this device facilitates efficient signal separation in RF communication systems requiring precise duplexing capabilities.

RF Multiplexers Feature Summary

• Utilizes Surface Acoustic Wave technology for high-performance signal filtering
• Provides high isolation levels between transmit and receive paths
• Features a miniature surface-mount footprint for space-constrained designs
• Supports dual-band operation with specific frequency ranges

RF Multiplexers Applications

• RF front-end modules for wireless communication devices
• Duplexing applications in narrowband radio systems
• Signal separation in transceiver circuits operating at specified frequencies

RF Multiplexers Procurement Notes

Verify the exact datasheet version and engineering change notices prior to procurement. Confirm that the application environment remains within the ±5 VDC maximum voltage rating. Ensure PCB layout accommodates the 1.80 mm x 1.40 mm x 0.50 mm package dimensions. Validate that the target system frequencies align strictly with the 746-756 MHz and 777-787 MHz operational bands defined by the manufacturer.

RF Multiplexers Selection Notes

Select this component when a small form factor SAW duplexer is required for dual-band RF applications. Consider its 60 dB to 63 dB isolation performance for systems needing effective signal separation. Evaluate the low insertion loss characteristics against system sensitivity requirements. Ensure compatibility with surface-mount assembly processes due to the leadless SMD package type.
