ADL8108ACPZN-R7

RF Amplifiers Overview

The ADL8108ACPZN-R7 is a GaAs low-noise amplifier (LNA) from Analog Devices Inc., operating within the 1 GHz to 8 GHz frequency range. It features integrated temperature sensing and enable/disable control capabilities, supporting high-efficiency applications. The device provides robust 50Ω input and output matching and utilizes a 16-lead LFCSP-WQ (3x3 mm) package. Key electrical specifications include a typical gain of 20 dB between 3 GHz and 4.5 GHz, an OIP3 of 35.5 dBm at 1 GHz to 4.5 GHz, and a noise figure of approximately 1 dB in the 3 GHz to 6 GHz band. It operates on a single 5V positive supply with a nominal quiescent current of 90 mA.

RF Amplifiers Procurement Notes

Verify that the suffix -R7 indicates reel packaging rather than cut tape or tray formats when sourcing. Confirm RoHS compliance status through official documentation. Ensure the supplier provides valid traceability data for the 16-lead LFCSP package. Check for moisture sensitivity level requirements during storage and handling. Validate that the component matches the specific Analog Devices manufacturing lot codes.

RF Amplifiers Selection Notes

Select this component for designs requiring wideband amplification from 1 GHz to 8 GHz with precise gain control. The integrated enable pin allows for dynamic power management in battery-constrained systems. Consider the 90 mA quiescent current draw against system power budgets. The 3mm x 3mm footprint suits space-constrained PCB layouts. Evaluate the 35.5 dBm OIP3 for linearity requirements in multi-carrier environments.

RF Amplifiers Part Context

This part belongs to the ADL8108 series of low-noise amplifiers designed for high-frequency RF applications. It complements other Analog Devices RF solutions by offering integrated sensing and control features not always present in standard LNAs. The device is engineered for reliability in harsh environments, supporting extended temperature ranges from -55°C to +125°C.

RF Amplifiers Replacement Considerations
