Product Descripꢀon
The BMT352 is a high dynamic range two-stage
power amplifier, housed in a lead-free/green/
RoHS compliant 3x3mm² QFN package. The
BMT352 uses a high reliability InGaP/GaAs HBT
process technology. The BMT352 is designed for
use where high linearity and gain are required.
The BMT352 is able to deliver over 22 dBm out-
put power from 3.0 to 4.0GHz while maintaining
superior ACLR performance with a few external
matching components. All devices are 100% RF/
DC screened.
