ADL8143ACPZN-CSL

RF Amplifiers Overview

The ADL8143ACPZN-CSL is a low noise amplifier (LNA) from Analog Devices Inc., designed for satellite communication applications within the 8 GHz to 14 GHz frequency range. It operates on a single positive supply voltage ranging from 1.2 V to 3.5 V, with a nominal quiescent current of 35 mA. The device delivers a typical gain of 28.5 dB and achieves a noise figure of 1 dB. Key performance metrics include an output power at 1 dB compression (P1dB) of 7.5 dBm and a third-order intercept point (OIP3) of 19.5 dBm. It features an input return loss of 11 dB and dissipates up to 950 mW of power. The component supports operation across an extended temperature range from -55°C to +125°C.

RF Amplifiers Procurement Notes

Verify the specific suffix 'CSL' against official Analog Devices documentation to confirm manufacturing lot or quality tier specifications. Ensure compatibility with the required operating voltage range of 1.2 V to 3.5 V. Confirm that the LFCSP-EP-8 package thermal pad connection meets your PCB layout requirements for heat dissipation. Check for moisture sensitivity level compliance during storage and handling procedures.

RF Amplifiers Selection Notes

Select this component when designing systems requiring low noise figures in the Ku-band spectrum. Consider the 28.5 dB gain for minimal cascaded noise impact. Evaluate the 35 mA current consumption against power budget constraints. The wide temperature range makes it suitable for aerospace or outdoor installations where standard commercial grades may fail.

RF Amplifiers Part Context

This part belongs to the ADL8143 series of low noise amplifiers. It shares functional similarities with other LNAs in the portfolio but is distinct in its specific frequency coverage and biasing options. The CSL suffix typically denotes a specific customer-specific logic or manufacturing variant defined by Analog Devices, differing from standard retail packages like the R7 reel.
