ADG918BRM-500RL7

Overview

The ADG918BRM-500RL7 is a wideband absorptive RF switch manufactured by Analog Devices Inc. It operates from DC to 4 GHz with a single 1.65 V to 2.75 V supply. The device features an SPDT topology in an 8-lead MSOP package. Key electrical parameters include 0.8 dB insertion loss at 1 GHz, 43 dB isolation at 1 GHz, and a maximum input power of 0.063 W. It supports CMOS/LVTTL control logic and consumes less than 1 µA of current.

Feature Summary

• Absorptive (matched) design providing high off-isolation
• Wideband operation up to 4 GHz with low insertion loss
• Single low-voltage power supply compatibility
• CMOS/LVTTL control logic interface

Applications

• Wireless communications systems
• Antenna diversity switching
• IF switching circuits
• Digital transceiver front end switching

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm packaging and tape specifications. Ensure the component matches the required voltage range and control logic levels for your specific application circuit before finalizing procurement orders.

Selection Notes

Select this component when absorptive matching is required to minimize reflections in RF signal paths. It is suitable for applications needing low power consumption and wide bandwidth within a compact surface-mount package. Verify that the operating frequency does not exceed the specified limits for optimal performance.

Part Context

This part belongs to the ADG918/ADG919 family of wideband switches. The ADG918 variant specifically offers an absorptive configuration, whereas the ADG919 provides a reflective option. Both utilize CMOS technology to achieve high isolation and low insertion loss across a broad frequency spectrum.
