AK1291

Product Overview

AK1291 is a AKM RF front-end / amplifier IC from AKM / Asahi Kasei Microdevices. In an RF design it is normally used as a RF receiver or front-end 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 AK1291 operating band per AKM datasheet; gain/noise/control data per exact datasheet; and low-voltage RF IC bias. Because RF amplifier parts are layout- and matching-sensitive, AK1291 should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
