ADL8103ACPZN

RF Amplifiers Overview

The ADL8103ACPZN is a GaAs low-noise amplifier (LNA) from Analog Devices Inc., designed for high-input power durability in RF and microwave applications. It operates within a frequency range of 6 GHz to 12 GHz, providing a typical gain of 25 dB and a noise figure of 1.7 dB at 8 GHz to 10 GHz. The device features an OIP3 of 32.1 dBm and supports up to +34 dBm RF input power survival. It requires a single positive supply voltage of 3.3 V with a nominal current consumption of 55 mA. Packaged in a compact 2 mm × 2 mm 8-pin LFCSP, it ensures robust performance in sensitive receiver front-ends.

RF Amplifiers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the received package matches the 8-LFCSP (2x2) specification and includes all required documentation. Ensure handling procedures comply with electrostatic discharge (ESD) protocols due to the sensitivity of the GaAs MMIC technology. Cross-reference the manufacturer part number against official datasheets to prevent substitution errors.

RF Amplifiers Selection Notes

Select this component when designing receivers requiring high linearity and exceptional input power tolerance within the 6 GHz to 12 GHz band. The ADL8103ACPZN is suitable for environments where strong interfering signals are present, as its high P1dB and OIP3 protect downstream stages. Consider the compact footprint and low current draw for space-constrained or battery-operated wireless infrastructure designs.
