ADG918BCPZ-REEL7

Overview

The ADG918BCPZ-REEL7 is a wideband RF switch IC manufactured by Analog Devices Inc. It operates as a single-pole double-throw (SPDT) switch or a 2:1 multiplexer with integrated 50 Ohm termination. The device supports frequencies from 0 Hz to 4 GHz, featuring an insertion loss of 0.8 dB and typical off-isolation of 43 dB at 1 GHz. Powered by a single supply voltage ranging from 1.65 V to 2.75 V, it utilizes CMOS technology. The component is housed in an 8-lead Lead Frame Chip Scale Package (LFCSP) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 2:1 multiplexer function with built-in 50 Ohm termination for simplified circuit design
• Provides high isolation performance across a wide bandwidth up to 4 GHz
• Operates on a low-voltage single power supply compatible with standard logic levels

Applications

• RF signal routing in wireless communication systems
• Test and measurement equipment requiring precise signal switching
• Base station infrastructure components

Procurement Notes

Verify the specific suffix REEL7 against official Analog Devices documentation to confirm packaging configuration and reel specifications. Ensure compatibility with LFCSP-8 footprint requirements during PCB layout. Confirm availability status through authorized distributors as supply may be restricted. Validate RoHS compliance details directly from the manufacturer's datasheet before procurement.

Selection Notes

Select this component when a compact SPDT switch with integrated impedance matching is required for frequencies up to 4 GHz. The low voltage operation suits battery-powered applications. Consider the LFCSP package size constraints and thermal dissipation capabilities relative to the application environment. Compare isolation and insertion loss metrics against alternative switches if higher frequency performance is needed beyond 4 GHz.

Part Context

This part belongs to the ADG918 series of wideband RF switches designed for general-purpose switching applications. It complements other Analog Devices RF solutions by offering a balance of performance and integration. The device is distinct from higher-frequency variants like the ADRF series, focusing on cost-effective broadband switching rather than ultra-high frequency operations.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADG918 family, such as the ADG919, which may offer different port configurations. Verify electrical parameter overlaps with competitors' SPDT switches if sourcing from multiple vendors.
