ADG936BCP-REEL

Overview

The ADG936BCP-REEL is a wideband RF switch IC from Analog Devices, featuring two independently selectable SPDT switches in a 4 mm × 4 mm LFCSP package. It operates on a single 1.65 V to 2.75 V CMOS supply and supports frequencies up to 4 GHz with -3 dB bandwidth. The absorptive topology provides high off-isolation of 36 dB at 1 GHz and low insertion loss of 0.9 dB from DC to 1 GHz. Control logic is compatible with CMOS and LVTTL standards. The device is designed for low power consumption and includes an REEL packaging format for automated assembly.

Feature Summary

• Wideband operation supporting frequencies up to 4 GHz
• Absorptive dual SPDT topology for high isolation
• Low insertion loss across the operational bandwidth
• CMOS/LVTTL control logic compatibility

Applications

• Wireless communication systems
• ISM band applications
• RF signal routing
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'BCP' indicates the LFCSP-20 (4x4) package variant distinct from the BRUZ TSSOP version. Confirm the '-REEL' designation matches the required tape-and-reel quantity for production runs. Ensure the voltage range aligns with system requirements as the device operates between 1.65 V and 2.75 V. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and lead times.

Selection Notes

Select this component when high isolation and low loss are critical for dual-channel RF switching up to 4 GHz. The absorptive design minimizes reflections compared to reflective alternatives. Consider the compact LFCSP footprint for space-constrained PCB layouts. Ensure the control interface supports the required CMOS or LVTTL voltage levels for seamless integration into digital control circuits.

Part Context

The ADG936 series comprises wideband analog switches built using a CMOS process. This specific model represents the dual SPDT variant optimized for high performance in wireless applications. It is part of a family that includes both absorptive (ADG936) and reflective (ADG936-R) options, offering designers flexibility based on impedance matching requirements.

Replacement Considerations

The ADG936BRUZ serves as a pin-compatible alternative in a 20-TSSOP package. For reflective switching needs, the ADG936-R variants may be considered. Verify package dimensions and thermal characteristics when substituting between LFCSP and TSSOP formats.
