BIG8
50-600 MHz Internally Matched IF Amplifier
Device Features
 OIP3 = 41.5 dBm @ 500 MHz
 Gain = 27 dB @ 140 MHz
 Output P1 dB = 21 dBm @ 140 MHz
 NF = 2.7 @ 70MHz at Demo Board
Product Description
BeRex’s BIG8 is a high performance InGaP/
GaAs HBT MMIC amplifier, internally
matched to 50 Ohms. The BIG8 is designed
for high linearity IF amplifier that require
excellent gain ,high OIP3 and flatness. It is
packaged in a RoHS-compliant with SOT-89
surface mount package.
Applications
 Base station Infrastructure/RFID
