LDMOS 2-stage integrated Doherty MMIC

The BLM9D2325-20AB is a 2-stage fully integrated Doherty MMIC solution using Ampleon's state of the art GEN9 LDMOS technology. The carrier and peaking device, input splitter and output combiner are integrated in a single package. This multiband device is perfectly suited as a final device in massive MIMO or small cell applications in the frequency range from 2300 MHz to 2500 MHz. Available in PQFN outline.

Features and benefits

  • Integrated input splitter
  • Integrated output combiner
  • Very high efficiency thanks to asymmetry
  • Designed for broadband operation (frequency 2300 MHz to 2500 MHz)
  • Independent control of carrier and peaking bias
  • Integrated ESD protection
  • Excellent thermal stability
  • Source impedance 50 Ω; high power gain
  • Compliant to Directive 2002/95/EC, regarding restriction of hazardous substances (RoHS)

Applications

  • RF power MMIC for multi-carrier and multi-standard GSM, W-CDMA and LTE base stations in the 2300 MHz to 2500 MHz frequency range.
