LDMOS 3-stage integrated Doherty MMIC

The BLM10D3438-35AB is a 3-stage fully integrated asymmetrical Doherty MMIC solution using Ampleon’s state of the art LDMOS technology. The carrier and peaking device, input splitter, output combiner and pre-match are integrated in a single package. This multiband device is perfectly suited as a final stage for small cells and massive MIMO applications in the frequency range from 3400 MHz to 3800 MHz. Available in PQFN outline.

Features and benefits

  • Integrated input splitter
  • Integrated output combiner
  • 30 Ω output impedance thanks to integrated pre-match
  • Very high efficiency thanks to asymmetry
  • Designed for wideband operation (frequency 3400 MHz to 3800 MHz)
  • Independent control of carrier and peaking bias
  • Integrated ESD protection
  • Source impedance 50 Ω; high power gain
  • For RoHS compliance see the product details on the Ampleon website


  • RF power MMIC for multi-carrier and multi-standard 5G base stations in the 3400 MHz to 3800 MHz frequency range
