ADG919BCP-REEL7

Overview

The ADG919BCP-REEL7 is an RF switch IC manufactured by Analog Devices Inc., designed for high-frequency signal routing applications. It features a single-pole double-throw (SPDT) configuration with a reflective multiplexer architecture, allowing for efficient signal path selection in radio frequency circuits. The device operates within a frequency range from 0 Hz to 4 GHz, providing versatile performance across various RF bands. Key electrical specifications include a typical insertion loss of 0.8 dB and a typical off-isolation of 43 dB, ensuring minimal signal degradation and effective channel separation. The component supports a wide operating temperature range from -40°C to +85°C, suitable for demanding industrial environments. It is housed in an 8-pin LFCSP package with an exposed pad, facilitating surface-mount installation.

Feature Summary

• Reflective multiplexer architecture for SPDT signal routing
• Operates up to 4 GHz frequency range
• Low insertion loss of 0.8 dB typical
• High off-isolation of 43 dB typical

Applications

• RF signal switching in communication systems
• Antenna switching modules
• Test and measurement equipment
• Wireless infrastructure components

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing. Confirm the 8-LFCSP package dimensions match your PCB footprint requirements. Check current availability status as supply may be limited or subject to factory special orders. Ensure compatibility with your system's voltage levels and control logic before integration.

Selection Notes

Select this component for applications requiring low-loss RF switching up to 4 GHz. Consider the reflective mux topology if impedance matching is critical for your signal paths. Evaluate the thermal performance within the specified -40°C to +85°C range. Compare against absorptive switches if isolation requirements exceed 43 dB.

Part Context

This part belongs to the ADG919 series of RF switches from Analog Devices. It is distinct from other ADG models like the ADG819 or ADG904 which offer different configurations such as WLCSP packages or absorptive topologies. The ADG919 specifically targets general-purpose SPDT RF switching needs with a balance of performance and size.
