ADL8111ACCZN

RF Amplifiers Overview

The ADL8111ACCZN is a broadband bypass amplifier from Analog Devices Inc., operating from 10 MHz to 8 GHz. It integrates a quad-throw (SP4T) non-reflective switch to provide multiple gain and linearity configurations. Key electrical parameters include a typical small-signal gain of 12.5 dB, a noise figure of 2.8 dB, and an output third-order intercept point (OIP3) of 34 dBm. The device operates on a single 5 V supply with a current consumption of 70 mA. It features a 11.5 dB gain setting, 17 dBm P1dB compression point, and 32 dBm OIP3 in specific modes. The component is housed in a 28-LGA (6x6 mm) package and supports surface-mount installation.

RF Amplifiers Procurement Notes

Verify the exact suffix (ACCZN) against the manufacturer's current datasheet to confirm pinout and packaging specifications. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the design-in process accounts for the 28-LGA thermal requirements and soldering profile suitable for LGA packages. Cross-reference the SPDT/SP4T switch control logic with system microcontroller capabilities.

RF Amplifiers Selection Notes

Select this component when a single-chip solution is required for wideband amplification with integrated switching capabilities. The ADL8111ACCZN is suitable for designs needing high linearity (34 dBm OIP3) and low noise (2.8 dB NF) without external switch components. Consider the 28-LGA package size constraints and the need for precise DC biasing at 5 V. Evaluate if the integrated SP4T switch meets the system's signal path complexity requirements compared to discrete alternatives.

RF Amplifiers Part Context

The ADL8111 series represents Analog Devices' approach to integrating RF switching with amplification. This family targets applications where board space is limited and multiple signal paths must be managed efficiently. The ACCZN variant specifically denotes the commercial temperature grade and LGA packaging format. It belongs to the broader category of general-purpose RF amplifiers designed for versatility in communication systems.

RF Amplifiers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult Analog Devices' official replacement guide or contact technical support for qualified alternatives that match the 28-LGA footprint and 10 MHz–8 GHz operational bandwidth.
