• Internally matched to 50 ohms

• Operated at 3.0V and 5.0V

• 36.2 dBm Output IP3 at 0dBm/tone at 1850 MHz

• 18.5dB Gain at 1850MHz

• 19.6dBm P1dB at 1850MHz

• 0.77 dB NF at 1850MHz on evaluation board

• Green/RoHS2 Compliant DFN8 2x2 Package

BeRex’s BLB02 is a high linearity LNA, based on

GaAs material with E-pHEMT process and pack-

aged in a RoHS2-compliant DFN 8L 2x2mm

2 Sur-

face mount package. It is designed for use where

low noise and high linearity are required and fea-

tures low noise and high OIP3 at Frequency range

of 1.5~2.7GHz. It is internally matched to 50 Ohms

without external matching components, with fast

enable switching speed for TD-LTE application. All

devices are 100% RF/DC tested and classified as

HBM ESD Class 1B.
