SPF5043Z

Product Overview

SPF5043Z is a Qorvo LNA / RF gain block amplifier from Qorvo. In an RF design it is normally used as a low-noise or high-linearity RF receive-chain gain stage, so the useful sourcing checks are not only the ordering code but also the operating band, gain behavior, output level, package footprint and bias conditions.

For this model, the key application data to verify are: exact frequency range depends on QPL/TQP/SPF base; Qorvo families cover cellular, CATV and general RF bands; gain, noise figure, OIP3 and P1dB must match the exact Qorvo datasheet; and low-voltage RF IC bias. Because RF amplifier parts are layout- and matching-sensitive, SPF5043Z should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
