LMS7002M
FPRF MIMO Transceiver IC
With Integrated Microcontroller
SUMMARY FEATURES
Field Programmable Radio Frequency (FPRF) chip
Dual transceiver ideal for MIMO
User programmable on the fly
Continuous coverage of the 100 kHz - 3.8 GHz RF frequency
range
Digital interface to baseband with on chip integrated 12 bit
D/A and A/D converters
Programmable RF modulation bandwidth up to
160 MHz using analog interface
Programmable RF modulation bandwidth up to
60 MHz using digital interface
Supports both TDD and full duplex FDD
LimeLightdigital IQ interface JEDEC JESD207 TDD and
FDD compliant
Transceiver Signal Processor block employs advanced
techniques for enhanced performance
Single chip supports 2x2 MIMO. Multiple chips can be used
to implement higher order MIMO
On-chip RF calibration circuitry
Fully differential baseband signals, analog IQ
Few external components
Low voltage operation, 1.25, 1.4 and 1.8V. Integrated LDOs
to run on a single 1.8V supply voltage
On chip integrated microcontroller for simplified calibration,
tuning and control
Integrated clock PLL for flexible clock generation and
distribution
User definable analog and digital filters for customised
filtering
RF and base band Received Signal Strength Indicator (RSSI)
261 pin aQFN 11.5x11.5 mm package
Power down option
Serial port interface
Low power consumption, typical 880mW in full 2x2 MIMO
mode (550mW in SISO mode) using external LDOs
Multiple bypass modes for greater flexibility
