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
