ADG936BRU-R

Overview

The ADG936BRU-R is a wideband, dual SPDT RF switch from Analog Devices Inc., designed for high-performance signal routing in wireless communications. It operates on a single 1.65 V to 2.75 V supply and features CMOS/LVTTL control logic. The device provides low insertion loss of 0.9 dB (DC to 1 GHz) and high off-isolation of 36 dB at 1 GHz. It supports frequencies up to 4 GHz with a -3 dB bandwidth. The component is housed in a 20-lead TSSOP package and consumes a maximum power of 1 µA.

Feature Summary

• Dual SPDT configuration with independently selectable switches
• Wideband operation supporting frequencies up to 4 GHz
• Low power consumption with single voltage supply requirement
• CMOS process technology ensuring high isolation and low insertion loss

Applications

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

Procurement Notes

Verify the specific suffix 'R' against current manufacturer catalogs, as this designation may indicate obsolete status or reflective topology variations. Confirm package integrity and lead-free compliance prior to integration. Cross-reference with active equivalents like the ADG936BRUZ-R series if long-term availability is required for production planning.

Selection Notes

Select this component for applications requiring wideband signal routing with minimal power draw. Ensure the system voltage aligns with the 1.65 V to 2.75 V range. Consider the reflective nature of the '-R' variant versus absorptive alternatives if impedance matching requirements differ. Validate thermal performance within the specified operating temperature range.

Part Context

This part belongs to the ADG936 family of wideband analog switches. It complements other variants such as the ADG936BRU (absorptive) and evaluation boards like EVAL-ADG936EBZ. The family targets ISM applications and IoT devices, offering a balance between speed, isolation, and power efficiency in a compact surface-mount package.

Replacement Considerations

The ADG936BRUZ-R is listed as a direct substitute for the ADG936BRU-R. Verify pinout compatibility and electrical specifications before substitution. Check for any changes in packaging or RoHS compliance status when transitioning between these specific part numbers.
