Shrink 5G Radios with NXP’s New Top-Side Cooling Modules for RF Power

NXP has introduced a family of 5G massive MIMO modules utilizing its innovative new top-side cooling package technology. The first products are designed for 32T32R 200 W radios, covering 3.3 GHz to 3.8 GHz frequency bands and leveraging the latest proprietary GaN technology manufactured in NXP’s new fab in Chandler, AZ. Smaller, thinner, and lighter systems will enable significant cost savings, plus more environmentally friendly base stations, while achieving the full performance benefits of 5G.

    Top-Side Cooling  Evaluation Board

    Features

  • Reduces radio thickness and weight
  • Enables fewer and shorter connectors
  • Removes the need for top-side RF shielding
  • Cleaner separation of thermal and RF paths
  • Lower thermal resistance
  • NXP RF top-side cooling technology enables thinner and lighter 5G massive MIMO radios, removing the need of the dedicated RF shield and separating thermal management from RF design. The first family of NXP top-side cooled devices are designed for 64T64R (320 W) or 32T32R (200 W) mMIMO radios covering 3.3 GHz to 3.8 GHz. These modules combine NXP’s internal LDMOS and GaN semiconductor technologies to enable high gain and efficiency with wideband performance, delivering 31 dB gain and 46 percent efficiency over 400 MHz of instantaneous bandwidth.

    These NXP GaN multi-chip evaluation boards are designed for the thin MIMO module series whose top-side cooling technology helps reduce the thickness and weight of the overall radio by more than 30 percent, while simplifying the design and manufacturing process.
