BeRex’s BG12B 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 BG12B 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.

*C1, C2, C3 =100 pF ± 5%; C4 = 1000 pF ± 5%; C5 = 10uF; L1 = 100nH
*39nH or higher value L1 improves RF performance at under 3GHz.
*Opꢀmum value of L1 may vary with board design.
