ADG936BRUZ-R

Overview

The ADG936BRUZ-R is a wideband reflective dual SPDT analog switch from Analog Devices Inc., manufactured using CMOS technology. It operates on a single 1.65 V to 2.75 V power supply and supports 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, with a -3 dB bandwidth extending to 4 GHz. It is housed in a 20-lead TSSOP package and consumes a maximum of 1 µA of power.

Feature Summary

• Reflective dual SPDT topology designed for high isolation applications
• Wideband operation supporting frequencies up to 4 GHz
• Low power consumption with standby current limited to 1 µA max
• Compatible with standard CMOS and LVTTL control logic levels

Applications

• Wireless communications systems
• Antenna diversity switching
• Digital transceiver front end switching
• High speed filter selection

Procurement Notes

Verify the suffix 'R' indicates the reflective variant distinct from the absorptive ADG936. Confirm the 20-TSSOP package type matches design requirements. Ensure voltage supply ranges between 1.65 V and 2.75 V. Check RoHS compliance status for environmental regulations. Validate operating temperature range covers -40°C to +85°C.

Selection Notes

Select this component when reflective switching behavior is required rather than matched termination. It suits designs needing wideband performance up to 4 GHz with minimal power draw. The CMOS process ensures compatibility with standard digital control interfaces. Consider the 20-TSSOP footprint for PCB layout constraints.

Part Context

This part belongs to the ADG936 family of wideband RF switches. The ADG936BRUZ-R specifically denotes the reflective version, whereas the ADG936BRUZ is the absorptive variant. Both share similar electrical characteristics but differ in shunt leg termination. The series targets general-purpose RF switching in compact wireless modules.

Replacement Considerations

The ADG936BRUZ serves as the primary alternative if absorptive switching is acceptable instead of reflective. Verify pinout compatibility between the reflective and absorptive variants before substitution.
