BeRex’s BG12C is a high performance InGaP/
GaAs HBT MMIC amplifier, internally
matched to 50 Ohms and uses a patented
temperature compensaꢀon circuit to pro-
vide stable current over the operaꢀng tem-
perature range without the need for exter-
nal components. The BG12C is designed for
high linearity gain block applicaꢀons that
require excellent gain flatness. It is packaged
in a RoHS-compliant with SOT-89 surface
mount package.
