Product Description
BeRex’s BIF1 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 BIF1 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
package.
Applications
 Base station Infrastructure/RFID
 Commercial/Industrial/Military wireless system
