ADG918BRM-REEL7

Overview

The ADG918BRM-REEL7 is a wideband absorptive RF switch manufactured by Analog Devices Inc., operating from DC to 2 GHz. It features a single-pole double-throw (SPDT) topology with 50-ohm impedance matching. Key electrical parameters include an insertion loss of 0.8 dB at 1 GHz and isolation of 43 dB at 1 GHz. The device supports a supply voltage range of 1.65 V to 2.75 V and consumes less than 1 µA in the off state. It utilizes CMOS/LVTTL control logic and is housed in an 8-lead MSOP package.

Feature Summary

• Absorptive SPDT design providing high isolation and low insertion loss across a wide bandwidth up to 4 GHz
• Low power consumption with standby current below 1 µA for battery-operated applications
• Compatible with standard CMOS and LVTTL control logic levels for easy integration

Applications

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

Procurement Notes

Verify the specific suffix REEL7 confirms tape and reel packaging when ordering. Ensure the component matches the 8-lead MSOP footprint requirements for your PCB layout. Confirm that the 1.65 V to 2.75 V supply range aligns with your system's voltage rails. Check for RoHS compliance status if required by your manufacturing standards. Validate the lead time availability as stock levels may vary.

Selection Notes

Select this component for applications requiring matched impedance absorption to minimize reflections. It is suitable for designs needing low insertion loss and high isolation in compact spaces. Consider the 8-lead MSOP package size constraints during board layout. Ensure control signals are compatible with the specified CMOS/LVTTL logic levels. Evaluate thermal performance within the -40°C to 85°C operating range.

Part Context

This part belongs to the ADG918/ADG919 family of wideband RF switches from Analog Devices. The ADG918 variant specifically offers absorptive characteristics, distinguishing it from reflective types. It complements other RF components in signal chain designs requiring precise routing and isolation. The family targets general-purpose RF switching in modern communication devices.

Replacement Considerations

The ADG918BRMZ-500RL7 is a confirmed public substitute offering identical functionality in a different packaging quantity configuration.
