5-800 MHz Internally Matched IF Amplifier

BIF5

BeRex’s BIF5 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 and a patented over volt-

age protection circuit to protect a internal

device. The BIF5 is designed for high linear-

ity IF amplifier that requires excellent gain,

high OIP3 and flatness. It is packaged in a

RoHS-compliant with SOT-89 surface mount
