Three-stage asymmetrical Doherty for 3.7 to 4.1GHz in PQFN

Author: EIS Release Date: Jul 12, 2021

Ampleon’s B10G3741N55D is a three-stage integrated asymmetrical Doherty MMIC, made on its GEN10 LDMOS process and aimed at small cells and massive MIMO.

For use across 3.7 to 4.1GHz, the carrier, peaking, input splitter, output combiner and pre-match are integrated in a single 8 x 8 x 2.1mm PQFN.

 

Gain is typically 34.7dB, and output power at 3dB gain compression is typically 47dBm (3.9GHz). As a Doherty amplifier, it is capable of withstanding a load mismatch corresponding to a VSWR of 10:1 (Vds 32V, Idq 70mA (carrier), Pi corresponding to Pload(3dB)-5dB under Zs=50Ω load, 4.1GHz, 25°C case).

 

Applications include multi-carrier and multi-standard 5G, W-CDMA and LTE basestations.
