ADG936BRU-R-REEL

Overview

The ADG936BRU-R-REEL is a wideband analog switch comprising two independently selectable SPDT switches fabricated using a CMOS process. It operates on a single 1.65 V to 2.75 V power supply and features low insertion loss of 0.9 dB from DC to 1 GHz. The device provides high off-isolation of 36 dB at 1 GHz and maintains a -3 dB bandwidth up to 4 GHz. It includes on-board CMOS control logic compatible with LVTTL inputs, eliminating the need for external driving circuitry. Power consumption is minimized to 1 µA maximum.

Feature Summary

• Reflective dual SPDT topology with 50 Ω terminated shunt legs
• Wideband performance extending to 4 GHz with low insertion loss
• Integrated CMOS/LVTTL control logic for direct interface compatibility
• Ultra-low power consumption suitable for battery-operated systems

Applications

• Wireless communications systems
• General-purpose RF switching
• Digital transceiver front end switching
• Antenna diversity switching modules

Procurement Notes

Verify that the specific suffix 'R' in the part number corresponds to the reflective variant rather than the absorptive version, as the base ADG936 series includes both types. Confirm the reel packaging specification matches the REEL designation in the ordering information. Ensure the voltage supply range aligns with the 1.65 V to 2.75 V requirement for proper operation of the internal CMOS control logic.

Selection Notes

Select this component when a reflective switch topology is required for dual-channel signal routing. The wide 4 GHz bandwidth supports applications beyond standard IF frequencies. The integrated control logic simplifies PCB layout by removing external driver requirements. Consider the TSSOP-20 package dimensions for space-constrained designs requiring surface-mount assembly.

Part Context

This component belongs to the ADG936 family of wideband RF switches manufactured by Analog Devices. The family differentiates between absorptive (ADG936) and reflective (ADG936-R) topologies. The BRU suffix indicates the commercial temperature grade and TSSOP-20 package configuration. The REEL suffix denotes the tape-and-reel shipping format for automated assembly processes.

FAQ

What is the difference between ADG936 and ADG936-R?

The ADG936 is an absorptive/matched dual SPDT with 50 Ω terminated shunt legs, while the ADG936-R is a reflective dual SPDT without termination.

Does the ADG936BRU-R require external control circuitry?

No, it features on-board CMOS control logic that is directly compatible with CMOS and LVTTL signals, eliminating the need for external drivers.
