5-800 MHz Internally Matched IF Amplifier

BG20B

BeRex’s BG20B is a high performance InGaP/

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 BG20B is designed for

high linearity IF amplifier that requires excel-

lent gain, high OIP3 and flatness. It is pack-

aged in a RoHS-compliant with SOT-89 sur-
