MGA-53543-BLKG

Product Overview

MGA-53543-BLKG is a Avago/Broadcom RF MMIC amplifier, LNA or gain block from Broadcom / Avago Technologies. In an RF design it is normally used as a small-signal RF gain stage or low-noise front end, 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: RF/microwave band is exact-base specific; ABA/ADA/MGA/AMMC families cover gain blocks, LNAs and microwave MMICs; gain, NF, P1dB and OIP3 must be matched to the base number and package suffix; and low-voltage RF IC bias; suffix usually identifies bulk/reel and RoHS package. Because RF amplifier parts are layout- and matching-sensitive, MGA-53543-BLKG should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
