ADG918BRMZ-REEL

Overview

The ADG918BRMZ-REEL is a wideband RF switch manufactured by Analog Devices Inc., featuring an absorptive topology and SPDT configuration. It operates within a frequency range of 0 Hz to 4 GHz, providing low insertion loss of 0.8 dB at 1 GHz and high off-isolation of 43 dB at 1 GHz. The device supports a single power supply voltage from 1.65 V to 2.75 V with CMOS/LVTTL control logic. Packaged in an 8-lead MSOP (RM-8) format, it ensures reliable performance across an operating temperature range of -40°C to +85°C.

Feature Summary

• Wideband operation up to 4 GHz with absorptive topology for matched impedance
• High off-isolation of 43 dB at 1 GHz combined with low insertion loss of 0.8 dB at 1 GHz
• Low power consumption requiring less than 1 µA current draw
• Compatible with CMOS and LVTTL control logic levels

Applications

• Wireless communications systems
• Antenna diversity switching
• Digital transceiver front end switching
• IF switching and tuner modules
• Dual-band applications

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and reel specifications. Ensure compatibility with standard surface mount assembly processes. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing environment. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component for designs requiring wideband RF switching with minimal signal reflection due to its absorptive nature. It is suitable for low-voltage applications powered by 1.65 V to 2.75 V supplies. Consider the 8-lead MSOP package for space-constrained PCB layouts. Verify that the control logic interface matches your system's CMOS or LVTTL standards to ensure proper switching functionality without additional level shifting circuitry.

Part Context

This part belongs to the ADG918/ADG919 series of wideband RF switches designed using CMOS technology. The ADG918 specifically denotes the absorptive variant, distinguishing it from reflective types. It is intended for general-purpose RF switching tasks where high isolation and low insertion loss are critical. The series supports various wireless and communication applications requiring efficient signal routing between antennas and receivers.
