SGA-5289Z

Product Overview

SGA-5289Z is a RFMD/Fairchild RF power amplifier or gain-block IC from RFMD / Qorvo. In an RF design it is normally used as a wireless transmit PA, driver or RF 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: frequency band follows the RFMD/RMPA/SGA/STA/SZA base family; gain, PAE, P1dB and linearity are exact-model datasheet parameters; and RF PA/gain-block bias per datasheet. Because RF amplifier parts are layout- and matching-sensitive, SGA-5289Z should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
