ADG919BRMZ

Overview

The ADG919BRMZ is a single-pole double-throw (SPDT) reflective RF switch IC manufactured by Analog Devices Inc. It operates within a frequency range of DC to 2 GHz, with specific high isolation performance optimized for the DC to 1 GHz band. The device supports a supply voltage range of 1.65 V to 2.75 V and functions across an industrial temperature range of -40°C to +85°C. Key electrical specifications include an insertion loss of 0.8 dB, an isolation level of 37 dB, a P1dB compression point of 17 dBm, and an input IP3 of 36 dBm at a test frequency of 1 GHz. It is housed in an 8-MSOP package.

Feature Summary

• Reflective topology design providing high isolation over the DC to 1 GHz frequency range
• On-board CMOS control logic for simplified interface integration
• Wideband switching capability utilizing CMOS process technology
• Low power consumption characteristics suitable for battery-operated systems

Applications

• Wireless LAN infrastructure equipment
• ISM band applications requiring low power operation
• RF signal chain routing in IoT devices
• General purpose RF switching in communication modules

Procurement Notes

Verify the specific suffix designation when ordering, as packaging options such as reel or cut tape may vary by distributor. Confirm that the 8-MSOP footprint matches your PCB layout requirements. Ensure supply voltage levels remain within the 1.65 V to 2.75 V operational window to maintain specified isolation and insertion loss parameters. Check RoHS compliance status if required for your manufacturing standards.

Selection Notes

Select this component when a reflective SPDT switch is required for frequencies up to 2 GHz. It is appropriate for designs prioritizing high isolation below 1 GHz. Consider the 8-MSOP package size for space-constrained surface-mount applications. Verify that the control voltage levels are compatible with the onboard CMOS logic before integration into the system architecture.

Part Context

The ADG919BRMZ belongs to the ADG918/ADG919 family of wideband RF switches from Analog Devices. These devices utilize a CMOS process to deliver high isolation and low insertion loss. The BRMZ suffix indicates the specific package type and temperature rating. This series is designed for applications demanding efficient RF signal routing with minimal power impact.

Replacement Considerations

The ADG902BRMZ is listed as a direct substitute option in some contexts, though it is an SPST configuration rather than SPDT. Verify pin compatibility and functional differences carefully. No other direct replacements are confirmed in the provided documentation.
