ADG919BRM-REEL7

Overview

The ADG919BRM-REEL7 is a wideband RF switch IC manufactured by Analog Devices Inc., housed in an 8-MSOP surface-mount package. It operates as a single SPDT reflective switch with a maximum frequency of 4 GHz. The device functions within a supply voltage range of 1.65 V to 2.75 V and supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a typical isolation of 37 dB at 1 GHz, insertion loss of 0.8 dB at 1 GHz, P1dB of 17 dBm, and IIP3 of 36 dBm. Switching performance features a maximum run time of 6.6 ns and a maximum settle time of 6.5 ns.

Feature Summary

• Provides high isolation levels suitable for demanding RF signal routing applications
• Operates on low supply voltages compatible with modern portable electronic systems
• Features fast switching speeds for dynamic signal path management

Applications

• Wireless communication infrastructure equipment
• Test and measurement instrumentation
• Mobile handset diversity antenna switching

Procurement Notes

Verify the specific suffix REEL7 against official Analog Devices documentation to confirm reel packaging specifications and tape dimensions. Ensure the component matches the required MSOP-8 footprint and thermal characteristics for your PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and compliance certifications such as RoHS3.

Selection Notes

Select this component when a compact, low-power RF switch is required for frequencies up to 4 GHz. Consider the 8-MSOP package size constraints and the 1.65 V to 2.75 V supply voltage requirements. Evaluate the 37 dB isolation and 0.8 dB insertion loss metrics against system link budget needs. Compare switching times against control logic capabilities to ensure adequate timing margins.

Part Context

This part belongs to the ADG919 series of wideband CMOS RF switches designed for ISM band applications. It shares architectural similarities with the ADG918 but offers extended bandwidth up to 4 GHz. The series is characterized by low power consumption and small form factor, targeting IoT and wireless sensor networks where space and energy efficiency are critical design parameters.
