Product Description
BeRex’s BG12B is a high performance InGa-
P/GaAs HBT MMIC amplifier, internally
matched to 50 Ohms and uses a patented
temperature compensation circuit to pro-
vide stable current over the operating tem-
perature range without the need for exter-
nal components. The BG12B is designed
for high linearity gain block applications
that require excellent gain flatness. It is
packaged in a RoHS-compliant with SOT-89
surface mount package.
