The B10G3438N55D from Ampleon is a 3-Stage LDMOS Asymmetrical Doherty MMIC that operates from 3400 to 3800 MHz. The carrier and peaking device, input splitter, output combiner, and pre-match are integrated into a single package. It delivers an output power of 47.5 dBm (at 3 dB compression point) with a power gain of 33.7 dB and has a drain efficiency of 37.3%. The transistor has been developed using Ampleon’s state-of-the-art GEN10 LDMOS technology. It is designed for wideband operation and provides independent control of the carrier and peaking bias.
The B10G3438N55D is available in an internally matched PQFN package with integrated ESD protection and requires a DC supply of 28 V. It has a 50-ohm source impedance and 30-ohm output impedance thanks to integrated pre-match. The transistor is suitable for use as a final stage in small cells (GSM, W-CDMA, and LTE) and massive MIMO applications.
