Analog Devices Inc. ADG918BRM RF Switch

The ADG918BRM from Analog Devices Inc. is a highly integrated RF switch designed for use in a variety of communication applications. This compact, monolithic device is part of the UltraCMOS® process, where advanced silicon technology is used to provide an unprecedented mix of performance and functionality.

The ADG918BRM is a reflective SPDT (Single Pole, Double Throw) switch that operates in the frequency range from 0 Hz (DC) to 4 GHz, making it suitable for a wide array of RF applications. It offers exceptional performance with very low insertion loss and high isolation between the ports, which is critical for maintaining signal integrity in complex RF systems.

This switch has an on-board CMOS control logic that allows the switch to be toggled using a single control input, simplifying the interface and reducing the control lines needed. The control voltage can be anywhere from 1.8 V to 5.5 V, making it compatible with a variety of logic families and systems.

The ADG918BRM comes in a compact Mini Small Outline Package (MSOP), which is ideal for space-constrained applications. Despite its small size, it delivers robust performance and is rated for operation over the extended industrial temperature range of -40°C to +85°C.
