ADG936BRU-500RL7

Overview

The ADG936BRU-500RL7 is a wideband analog switch featuring two independently selectable SPDT switches fabricated using CMOS technology. It provides high isolation and low insertion loss up to 1 GHz, with a -3 dB bandwidth extending to 4 GHz. The device operates on a single 1.65 V to 2.75 V power supply and includes CMOS/LVTTL control logic. It offers 36 dB isolation at 1 GHz and 0.9 dB insertion loss from DC to 1 GHz. The component is housed in a 20-lead TSSOP package and consumes a maximum of 1 µA of power.

Feature Summary

• Absorptive dual SPDT architecture with 50 Ω terminated shunt legs for matched impedance
• Wideband operation supporting frequencies up to 4 GHz with low insertion loss
• Single low-voltage power supply compatibility with standard CMOS control logic

Applications

• Wireless communications systems
• General-purpose RF switching
• Dual-band applications
• High-speed filter selection
• Antenna diversity switching

Procurement Notes

Verify the specific suffix '500RL7' against official Analog Devices documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the ordering part number matches the exact voltage and package variant required for your design. Cross-reference the datasheet revision date to confirm current electrical characteristics and mechanical drawings are applicable to the manufactured batch.

Selection Notes

Select this component when an absorptive (matched) SPDT topology is required rather than reflective switching. The 50 Ω internal termination distinguishes it from non-terminated variants like the ADG936-R. Verify that the system power supply remains within the 1.65 V to 2.75 V range and that control signals are compatible with CMOS or LVTTL logic levels for proper operation.

Part Context

This part belongs to the ADG936 family of wideband RF switches from Analog Devices. It is specifically the absorptive version packaged in a 20-lead TSSOP. It differs from the ADG936-R, which is a reflective switch without internal termination. The '500RL7' suffix indicates the specific reel quantity and packaging format supplied by the manufacturer.

FAQ

What is the difference between the ADG936BRU and ADG936-R?

The ADG936BRU is an absorptive dual SPDT switch with 50 Ω terminated shunt legs, whereas the ADG936-R is a reflective dual SPDT switch without internal termination.

What is the maximum operating frequency specified for this switch?

The device is characterized as a wideband switch with a -3 dB point at 4 GHz, though key parameters like isolation are typically specified at 1 GHz.
