Ampleon has expanded the power envelope for macro drivers with the introduction of the B11G1822N120D, a dual-section, two-stage LDMOS Doherty MMIC designed for macro base station applications. By integrating two complete Doherty signal paths into a single compact footprint, the device extends output power capability, simplifies RF design, and enables varied system configurations.
Operating across the 1800 MHz to 2200 MHz frequency range, the B11G1822N120D aligns with industry trends toward higher power density and 6G-ready macro infrastructure, providing integrated functionality for next-generation wireless networks.
As base station designs continue to evolve toward higher capacity and increased flexibility, RF engineers are under pressure to deliver consistent performance across multiple bands and deployment scenarios while reducing footprint and design complexity. Traditional driver solutions often require multiple discrete devices and careful balancing between paths, increasing both design effort and system variability. The B11G1822N120D addresses these challenges by integrating dual Doherty sections, including carrier and peaking amplifiers, input splitting, output combining, and pre-matching into a single MMIC.
Under typical W-CDMA operating conditions, the device delivers 37 dBm average output power with 30 dB gain and drain efficiency up to 27 %, while maintaining linearity with ACPR levels of -40 dBc. This combination of high gain and linear performance enables efficient amplification of high-PAR signals, which may reduce the need for additional driver stages.
The B11G1822N120D is designed for multi-band and multi-standard operation. Its ability to handle large instantaneous bandwidths, combined with independent control of carrier and peaking bias, allows designers to optimize performance across varying operating conditions while maintaining consistent efficiency and linearity.
A key advantage of the device is its dual-section architecture, which enables multiple RF design approaches and system configurations. Designers can leverage the two integrated Doherty paths to support higher output power levels, parallel operation, or redundancy, depending on system requirements. This flexibility can reduce design complexity and enable efficient use of board space in high-density radio units.
Robustness remains critical in real-world deployments, and the B11G1822N120D is designed to withstand load mismatch conditions up to 10:1 VSWR under defined operating conditions, to maintain operation in RF environments with impedance variations. Its thermal performance, with junction-to-case thermal resistance as low as approximately 2.1 K/W under typical conditions, supports operation at high power levels.
