ADG901BCPZ-500RL7

Overview

The ADG901BCPZ-500RL7 is an RF switch IC manufactured by Analog Devices Inc., designed for high-frequency signal routing applications. It features a single-pole single-throw (SPST) configuration with integrated 50 Ohm termination, ensuring impedance matching within RF circuits. The device operates across a frequency range from 0 Hz to 2.5 GHz, providing reliable signal transmission in demanding environments. Key electrical characteristics include a maximum insertion loss of 0.8 dB and typical off-isolation of 43 dB, which supports effective signal isolation when the switch is deactivated. The component is housed in an LFCSP-8 surface-mount package, suitable for automated assembly processes. It functions within a temperature range of -40°C to +85°C, making it appropriate for industrial and commercial use cases requiring stable RF performance.

Feature Summary

• Integrates 50 Ohm termination for direct impedance matching without external components
• Provides high off-isolation to minimize signal leakage in the deactivated state
• Supports wideband operation from DC up to 2.5 GHz for versatile RF applications
• Utilizes low-profile surface-mount packaging for compact board design

Applications

• RF signal routing in wireless communication systems
• Test and measurement equipment requiring precise signal switching
• Mobile device front-end modules for antenna selection
• Instrumentation systems needing isolated signal paths

Procurement Notes

Verify the exact part number suffix RL7 against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with LFCSP-8 footprint dimensions and thermal requirements during PCB layout. Cross-reference moisture sensitivity levels and reflow soldering profiles with current manufacturing notices. Confirm availability status through authorized distributors as supply conditions may vary. Validate that the 50 Ohm termination aligns with system impedance requirements before integration.

Selection Notes

Select this component when a compact SPST switch with built-in 50 Ohm termination is required for frequencies up to 2.5 GHz. Consider the low insertion loss and high isolation metrics for applications demanding signal integrity. Evaluate the LFCSP-8 package size against available board space constraints. Assess the operating temperature range to ensure suitability for the intended environmental conditions. Compare power dissipation characteristics if thermal management is a critical design factor.
