PA module with bias controller

The G1M3438P70C is a fully integrated Doherty Power Amplifier Module (PAM) covering the 3.4 to 3.8 GHz frequency range with 70W peak power and using Ampleon’s state-of-the-art GaN technology. The module integrates a bias control IC (BCIC) with a calibrated and pre-configured Look-Up Table (LUT) for autonomous gate bias temperature-compensation and an I2C communication interface. It features 50 Ω input / 50 Ω output impedances, monitoring and control functions, as well as a failure reporting system.

This multi-band power amplifier module is designed to address the high performance 5G massive MIMO requirements, and TDD and FDD systems in a small 12 mm x 8 mm package.

Features and benefits

  • Fully Integrated Doherty 50 Ω input / 50 Ω output
  • Designed for large RF and instantaneous bandwidth operation (up to 400 MHz)
  • Integrated temperature sensor for in-situ probing
  • Integrated non-volatile memory for start-up configuration recall
  • Pre-configured Look-Up Table (LUT) with independent DACs for autonomous gate
  • voltage regulation over temperature
  • User-reconfigurable operation through I2C interface
  • Monitoring and control functions with failure reporting system
  • Integrated fast TDD gate switches
  • 12 mm x 8 mm LGA surface mount package
  • For RoHS compliance see the product details on the Ampleon website

Applications

  • RF power module for multi-carrier massive MIMO base stations in the 3400 MHz to 3800 MHz frequency range.
