F1458NKGK8

Product Overview

F1458NKGK8 is a Renesas RF amplifier / VGA / driver IC from Renesas Electronics. In an RF design it is normally used as a receiver or transmitter RF/IF 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: Renesas F-series frequency/band is exact-number specific, often used in infrastructure RF chains; gain, NF, OIP3 and control range are listed per exact Renesas base; and RF IC supply and control pins per package. Because RF amplifier parts are layout- and matching-sensitive, F1458NKGK8 should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
