BIF5
5-800 MHz Internally Matched IF Amplifier
Device Features
 OIP3 = 43.0 dBm @ 70 MHz
 Gain = 17.5 dB @ 70 MHz
 Output P1 dB = 20.5 dBm @ 70 MHz
 50 Ω Cascadable
 Patented temperature compensation
 Patented over voltage protection
 Lead-free/RoHS-compliant SOT-89 SMT package
Product Description
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
package.
Applications
 Base station Infrastructure/RFID
 Commercial/Industrial/Military wireless system
