ADG918BRMZ-REEL7

Overview

The ADG918BRMZ-REEL7 is a wideband absorptive RF switch manufactured by Analog Devices Inc. It operates from DC to 4 GHz with a single-pole double-throw (SPDT) configuration. Key electrical parameters include an insertion loss of 0.8 dB at 1 GHz and typical off-isolation of 43 dB at 1 GHz. The device functions on a single supply voltage ranging from 1.65 V to 2.75 V, consuming less than 1 µA of power. It features CMOS/LVTTL control logic and is housed in an 8-lead MSOP package.

Feature Summary

• Absorptive topology providing matched impedance characteristics for reduced signal reflection
• Wideband operation supporting frequencies up to 4 GHz with high isolation performance
• Ultra-low power consumption suitable for battery-operated wireless applications

Applications

• Wireless communications systems
• Antenna diversity switching
• Digital transceiver front-end switching
• High-speed filter selection modules

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary. Ensure the order matches the exact part number to guarantee correct packaging quantity and handling specifications.

Selection Notes

Select this component for designs requiring low insertion loss and high isolation in a compact surface-mount package. The absorptive nature makes it suitable for applications where signal reflections must be minimized. Verify that the system control logic aligns with the specified CMOS/LVTTL input requirements and that the operating temperature range meets environmental constraints.

Part Context

This part belongs to the ADG918/ADG919 family of wideband switches designed for general-purpose RF switching. The ADG918 variant specifically offers absorptive characteristics, distinguishing it from reflective switch alternatives within the same product line. It is engineered for integration into modern wireless infrastructure and portable devices.

Replacement Considerations

The ADG918BRMZ-500RL7 is a confirmed substitute offering identical functionality but supplied in a different reel quantity configuration.
