ADG902BRM

Overview

The ADG902BRM is a wideband, single-pole single-throw (SPST) radio frequency switch manufactured by Analog Devices Inc. utilizing CMOS technology. It operates within a frequency range of 0 Hz to 2.5 GHz and supports a supply voltage between 1.65 V and 2.75 V. The device provides 40 dB isolation at 1 GHz with an insertion loss of 0.8 dB. Key performance metrics include a P1dB of 17 dBm and an IIP3 of 36 dBm. It features a reflective topology and is housed in an 8-MSOP surface-mount package. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Utilizes CMOS process technology for high isolation and low insertion loss
• Provides wideband switching capability up to 2.5 GHz
• Operates on a single low-voltage power supply ranging from 1.65 V to 2.75 V

Applications

• RF signal routing in wireless communication systems
• Antenna switching applications
• Test and measurement equipment signal paths
• General-purpose RF circuitry requiring low power consumption

Procurement Notes

Verify the current manufacturing status as the ADG902BRM is listed as obsolete or not recommended for new designs. Confirm availability through authorized distributors or check for direct replacement options such as the ADG902BRMZ. Ensure that the specific package variant matches the required footprint for existing PCB layouts. Validate datasheet specifications against the latest official Analog Devices documentation before finalizing procurement decisions.

Selection Notes

Select this component when a low-power, wideband SPST switch is required for frequencies up to 2.5 GHz. Consider the 8-MSOP package size for space-constrained designs. Evaluate the 40 dB isolation and 0.8 dB insertion loss against system requirements. Ensure the operating temperature range meets environmental conditions. Compare performance metrics like P1dB and IIP3 with alternative switches if higher linearity is needed.

Part Context

The ADG902BRM belongs to the ADG901/ADG902 family of wideband CMOS switches designed by Analog Devices. These devices are engineered to offer high isolation and low insertion loss across a broad frequency spectrum. The family targets applications demanding efficient RF signal management with minimal power consumption, suitable for portable and battery-operated wireless devices.

Replacement Considerations

The ADG902BRMZ is identified as a direct substitute for the ADG902BRM. Verify pin compatibility and electrical parameter equivalence before substitution. Check for any changes in packaging or lead-free compliance status associated with the replacement part number.
