Product Description
RFMD's RFLA1018 is an analog-controlled voltage-variable gain amplifier featuring
high linearity and very low noise figure. This LNA with bypass mode and variable
attenuator provides a minimum 35dB of dynamic gain range. The RFLA1018 has a
3.3V control range with maximum gain at 0V. The LNA is temperature compensated
to reduce gain variation. A noise figure of 0.65dB and an IIP3 of 2dBm make this
component ideal for receiver input lineups. The RFLA1018 is packaged in a small
8.0mm x 8.0mm leadless laminate MCM. This module is internally matched to 50
on all RF ports, making it easy to use with no external matching components
required.
