ADG919BRMZ-REEL

Overview

The ADG919BRMZ-REEL7 is a reflective single-pole double-throw (SPDT) RF switch IC from Analog Devices, designed for high-isolation signal routing. It operates within a frequency range of 0 Hz to 4 GHz, with optimal performance up to 1 GHz. The device supports a supply voltage between 1.65 V and 2.75 V, ensuring low power consumption with a maximum power dissipation of 2.5 µW. Key electrical parameters include an insertion loss of 0.8 dB and isolation of 37 dB at 1 GHz. It features a turn-on time of 6.5 ns and a turn-off time of 6.6 ns. The component is housed in an 8-MSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Reflective SPDT topology providing high isolation over the DC to 1 GHz frequency range
• Ultra-low power consumption suitable for battery-operated wireless applications
• On-board CMOS control logic compatible with standard digital interfaces
• Fast switching speeds with minimal propagation delay for dynamic signal routing

Applications

• RF signal path switching in wireless communication modules
• Diversity antenna switching systems for mobile devices
• ISM band signal routing in IoT sensor nodes
• Test and measurement equipment requiring low-loss RF switching

Procurement Notes

Verify the specific suffix REEL7 confirms tape-and-reel packaging when sourcing. Confirm that the 8-MSOP package dimensions match your PCB footprint requirements. Ensure the supply voltage range aligns with your system's rail voltages. Check RoHS compliance status for environmental regulations. Validate the operating temperature range against your application's thermal constraints before finalizing procurement.

Selection Notes

Select this component when high isolation is critical for the DC to 1 GHz band. The reflective topology differs from absorptive switches, affecting termination requirements. Consider the 4 GHz upper limit if higher frequency operation is occasionally needed. The low supply voltage range suits modern low-voltage digital systems. Evaluate the MSOP package size against available board space constraints.

Part Context

The ADG919 belongs to Analog Devices' family of wideband CMOS RF switches. It complements the absorptive ADG918 variant, offering a reflective alternative for different impedance matching strategies. Both share similar pinouts and control logic, facilitating design flexibility. The series targets compact wireless designs requiring reliable signal integrity.

Replacement Considerations

The ADG918BRMZ serves as a functional substitute but utilizes an absorptive topology rather than reflective. Verify impedance matching network adjustments are required when swapping between these variants. Other family members may offer different frequency ranges or power levels.
