ADG936BRU-R-REEL7

Overview

The ADG936BRU-R-REEL7 is a wideband RF switch IC from Analog Devices, featuring two independently selectable Single-Pole Double-Throw (SPDT) switches. It operates with a supply voltage range of 1.65 V to 2.75 V 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. It functions up to 4 GHz with a -3 dB bandwidth limit. Packaged in a 20-lead TSSOP, it consumes a maximum power dissipation of 1 µA. The component is designed for applications requiring reliable signal routing in wireless communications and general-purpose RF switching environments.

Feature Summary

• Dual SPDT configuration with absorptive or reflective options
• Wideband operation supporting frequencies up to 4 GHz
• Low power consumption with single supply voltage compatibility
• High isolation and low insertion loss characteristics

Applications

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

Procurement Notes

Verify the specific suffix 'R' indicates the reflective variant against the absorptive ADG936. Confirm the 20-TSSOP package type matches design requirements. Ensure the reel packaging format aligns with assembly line capabilities. Check RoHS compliance status for regulatory adherence. Validate operating temperature range suitability for the intended environment.

Selection Notes

Choose this component when dual independent SPDT switching is required within a compact footprint. The low insertion loss and high isolation make it suitable for sensitive RF paths. Consider the 1.65 V to 2.75 V supply range for compatibility with modern low-voltage digital interfaces. Evaluate the 4 GHz bandwidth against system frequency needs. Compare with the absorptive version if impedance matching termination is preferred over reflection management.

Part Context

This part belongs to the ADG936 series of wideband analog switches manufactured by Analog Devices. It utilizes a CMOS process to achieve high performance in a small form factor. The series includes both absorptive and reflective variants to suit different circuit topologies. The BRU suffix denotes the specific temperature grade and package style within the product family.

Replacement Considerations

The ADG936BRUZ-REEL7 serves as a direct functional substitute, offering identical electrical specifications but potentially differing in lead-free compliance or specific manufacturing lot details. Verify pinout compatibility and thermal characteristics before substitution.
