LMS7002M Documentation 

======================



The LMS7002M is Lime’s second-generation field programmable RF (FPRF) transceiver IC, with extended functionality to cover a greater range of frequencies and applications.



The device uses state of the art transceiver design in CMOS technology to significantly reduce cost and power consumption. It integrates a dual transceiver architecture to support 2×2 MIMO along with on-chip digital signal processing functions. The LMS7002M can run on any mobile communications and wireless standard – including all 2G, 3G and 4G variants and WiFi – both licensed and unlicensed.



Summary of features:



* Field Programmable Radio Frequency (FPRF) chip

* Dual transceiver ideal for MIMO

* User programmable on the fly

* Continuous coverage of the 100kHz-3.8GHz 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 120MHz using analog interface

* Programmable RF modulation bandwidth up to 56MHz using digital interface

* Supports both TDD and full duplex FDD

* LimeLight™ digital IQ interface – JEDEC JESD207 TDD and FDD compliant

* Transceiver Signal Processor block employs advanced techniques for enhanced performance

* Single chip supports 2×2 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)

* 261pin aQFN 11.5×11.5 mm package

* Power down option

* Serial port interface

* Low power consumption, typical 880mW in full 2×2 MIMO mode (550mW in SISO mode) using external LDOs

* Multiple bypass modes for greater flexibility
