HFA3424IB

Product Overview

HFA3424IB is a Harris/Intersil RF or high-speed amplifier IC from Harris / Intersil. In an RF design it is normally used as a RF front-end, IF or high-speed analog 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 operating band/bandwidth must be matched to the HFA/ISL base; gain/noise/linearity depends on exact base and application circuit; and analog/RF supply rails per datasheet. Because RF amplifier parts are layout- and matching-sensitive, HFA3424IB should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
