ADG936BRUZ-REEL

Overview

The ADG936BRUZ-REEL is a wideband RF switch IC from Analog Devices, featuring two independently selectable SPDT switches in a 20-lead TSSOP package. It operates on a single 1.65 V to 2.75 V supply with CMOS/LVTTL control logic. The device provides high off-isolation of 36 dB at 1 GHz and low insertion loss of 0.9 dB from DC to 1 GHz. It supports frequencies up to 4 GHz with a -3 dB point at that limit. Power consumption is minimal at 1 µA max. The absorptive design includes 50 Ω terminated shunt legs for matched performance.

Feature Summary

• Absorptive dual SPDT configuration with 50 Ω terminated shunt legs
• Wideband operation supporting frequencies up to 4 GHz
• CMOS/LVTTL compatible control logic eliminating external circuitry needs
• Low power consumption suitable for wireless applications

Applications

• Wireless communications systems
• General-purpose RF switching
• Antenna diversity switching
• IF switching in digital transceivers
• High-speed filter selection

Procurement Notes

Verify the specific suffix REEL against official Analog Devices documentation to confirm reel quantity and tape specifications. Ensure the absorptive variant (ADG936) matches the reflective requirement if applicable, as the -R suffix denotes reflective type. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Cross-reference the 20-TSSOP package dimensions with PCB footprint requirements to ensure mechanical compatibility.

Selection Notes

Select this component when low insertion loss and high isolation are critical for signal integrity in the 1 GHz range. The absorptive topology is preferred over reflective types to prevent signal reflections from affecting source impedance. Verify that the 1.65 V to 2.75 V supply voltage aligns with the system's power rails. Consider the 4 GHz bandwidth if higher frequency extension beyond 1 GHz is required for future-proofing or wider channel utilization.

Part Context

The ADG936 series comprises wideband analog switches designed for high-frequency applications. The BRUZ suffix indicates a specific tape-and-reel packaging format within the TSSOP-20 family. This part belongs to the broader ADG936 product line, which differentiates between absorptive (ADG936) and reflective (ADG936-R) topologies. The BRU variant specifically refers to the standard commercial temperature grade version housed in the TSSOP package.

Replacement Considerations

The ADG936BRU-REEL serves as a direct equivalent in terms of functionality and packaging. For reflective applications, the ADG936BRU-R-REEL7 is the appropriate substitute. Ensure that any replacement maintains the same 20-TSSOP footprint and electrical characteristics regarding isolation and insertion loss.
