ADG918BRM-REEL

Overview

The ADG918BRM-REEL is a wideband absorptive RF switch manufactured by Analog Devices Inc. It operates as a single-pole double-throw (SPDT) device with a frequency range of 0 Hz to 2 GHz. Key electrical parameters include an insertion loss of 0.8 dB and isolation of 37 dB at 1 GHz. The component supports a supply voltage of 1.65 V to 2.75 V and features low power consumption below 1 µA. It utilizes 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 capability extending up to 4 GHz with high off-isolation performance
• Low power consumption design suitable for battery-operated wireless applications
• Compatibility with standard CMOS and LVTTL control logic levels

Applications

• Wireless communications systems
• General-purpose RF switching
• Antenna diversity switching
• IF switching modules

Procurement Notes

Verify the specific suffix against official documentation, as packaging variations such as REEL or TR may exist. Confirm the exact part number matches the required tape and reel specifications for automated assembly. Ensure compatibility with the intended supply voltage range and control logic levels before integration into the final design.

Selection Notes

Select this component for applications requiring low insertion loss and high isolation in a compact surface-mount package. The absorptive nature makes it suitable for environments where signal reflections must be minimized. Verify that the operating temperature range meets the environmental requirements of the target system.

Part Context

This component belongs to the ADG918/ADG919 family of wideband switches from Analog Devices. These devices are designed using a CMOS process to offer high performance in small form factors. The ADG918 specifically provides absorptive switching, distinguishing it from reflective variants within the same product line.

Replacement Considerations

The ADG918BRMZ-500RL7 is a confirmed public substitute available from Analog Devices Inc.
