LDMOS 1-stage integrated Doherty MMIC

The BLM9D0708-05AM is a 1-stage 5 W 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 device in the frequency range from 728 MHz to 821 MHz. Available in LGA outline.

Features and benefits

  • Integrated input splitter
  • Integrated output combiner
  • Very high efficiency
  • Designed for broadband operation (frequency 728 MHz to 821 MHz)
  • Independent control of carrier and peaking bias
  • Integrated ESD protection
  • Excellent thermal stability
  • High power gain, input and output matched to impedance 50 Ω
  • For RoHS compliance see the product details on the Ampleon website

Applications

  • RF power MMIC for multi-carrier and multi-standard GSM, W-CDMA, LTE and NR small cell base stations in the 728 MHz to 821 MHz frequency range
