LMS8001-Companion

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’’)
