ADG901BRMZ-REEL7

Overview

The ADG901BRMZ-REEL7 is an absorptive RF switch IC manufactured by Analog Devices Inc., designed for single-pole single-throw (SPST) applications with a 50-ohm termination. It operates within a frequency range of 0 Hz to 4.5 GHz, offering an insertion loss of 0.8 dB and typical off-isolation of 40 dB. The device supports a supply voltage range from 2.7 V to 5.5 V and functions across temperatures from -40°C to +85°C. Packaged in an 8-lead MSOP format, it integrates control logic for simplified interface.

Feature Summary

• Absorptive switching architecture minimizes signal reflections
• Integrated control logic simplifies system interfacing
• Capable of passing DC signals without blocking capacitors

Applications

• RF signal routing in communication systems
• Test and measurement equipment signal paths
• Wireless infrastructure component switching

Procurement Notes

Verify availability status as the part may be subject to limited supply or factory special orders. Confirm that the REEL7 suffix corresponds to the required tape and reel packaging configuration for automated assembly processes. Ensure compatibility with standard SMD/SMT placement equipment specifications.

Selection Notes

Select this component when absorptive switching characteristics are required to maintain signal integrity in high-frequency applications. Consider the 8-lead MSOP package constraints for board space limitations. Evaluate the 0.8 dB insertion loss against system budget requirements and verify that the 4.5 GHz upper frequency limit meets operational bandwidth needs.

Part Context

This part belongs to the ADG901 series of general-purpose RF switches. It is distinct from reflective switch variants like the ADG902, utilizing an absorptive design to terminate unused ports effectively. The BRMZ suffix indicates the specific temperature grade and package type within the broader product family.

Replacement Considerations

Direct substitutes include other absorptive SPST RF switches from Analog Devices such as the ADG902 series, though functional differences exist between absorptive and reflective topologies. Verify pinout compatibility and electrical parameter alignment before substitution.
