LMS8001-Companion

LimeSDR board

The LMS8001-Companion board provides a highly integrated, highly configurable, four-channel frequency shifter platform, utilising the LMS8001A integrated circuit. One of the typical applications is extending Lime Micro transceiver family RF frequency range up to 10 GHz.

  • LMS8001A Integrated Circuit
    • Single chip up/down RF frequency shifter with continuous coverage up to 10 GHz RF output range
    • Four independent highly reconfigurable RF paths all driven by the same LO
    • Fully differential signals
    • Few external components
    • Low voltage operation, 1.2 and 1.8V. Integrated LDOs to run on a single 1.8 V supply
    • 56-pin QFN package
    • Serial Port Interface
    • Power down control available via ENABLE pins and/or equivalent SPI registers
    • Synchronous loading of pre-set operation profiles by GPIO pins. More options are also available using corresponding SPI registers
  • Connections
    • 4 x SMA connectors - RF
    • 4 x UFL connectors – RF
    • 1 x SMA connector – External LO
    • 1 x UFL connector – External clock reference
  • RF Matching
    • Channel A Input (UFL) – 1–3 GHz broadband, using TC1-1-13M+ balun
    • Channel B Input (UFL) – 1–3 GHz broadband, using TC1-1-13M+ balun
    • Channel C Input (SMA) – 10 GHz band, using NCR2-113+ balun
    • Channel D Input (SMA) – 5 GHz band, using NCR2-113+ balun
    • Channel A Output (SMA) – 10 GHz band, using NCR2-113+ balun
    • Channel B Output (SMA) – 5 GHz band, using NCR2-113+ balun
    • Channel C Output (UFL) – 1–3 GHz broadband, using TC1-1-13M+ balun
    • Channel D Output (UFL) – 1–3 GHz broadband, using TC1-1-13M+ balun
  • USB Interface
    • USB - mini B (STM32 controller STM32F105RBT6)
  • Clock System
    • 40MHz on board VCTCXO
    • Possibility to lock VCTCXO to external clock
  • Board Size
    • 60mm x 100mm (2.36’’ x 3.94’’)
