LDMOS 2-stage power MMIC

The BLM7G1822S-40PB(G) is a dual section, 2-stage power MMIC using Ampleon’s state of the art GEN7 LDMOS technology. This multiband device is perfectly suited as general purpose driver or small cell final in the frequency range from 1805 MHz to 2170 MHz. Available in gull wing or straight lead outline.

Features and benefits

  • Designed for broadband operation (frequency 1805 MHz to 2170 MHz)
  • High section-to-section isolation enabling multiple combinations
  • Integrated temperature compensated bias
  • Biasing of individual stages is externally accessible
  • Integrated ESD protection
  • Excellent thermal stability
  • High power gain
  • On-chip matching for ease of use
  • For RoHS compliance see the product details on the Ampleon website

Applications

RF power MMIC for W-CDMA base stations in the 1805 MHz to 2170 MHz frequency range. Possible circuit topologies are the following:

  • Dual section or single ended
  • Doherty
  • Quadrature combined
  • Push-pull
