LMS7002MThe 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.

The LMS7002M is ideal for a wide range of consumer and professional applications, including:

  • Small cell communications equipment
  • M2M networks
  • Broadband wireless
  • Netbooks and tablet PCs
  • Test equipment
  • Open source radio
  • Military
  • SDR
  • Cognitive radio

Lime’s proven FPRF technology has been used by private companies, government and military organisations to create a myriad of wireless broadband technologies, from whitespace radios to disaster relief networks to communications infrastructure devices.

Highlights

Configurability

The LMS7002M has a continuous operation spectrum of 100khz to 3.8GHz, and is software configured to operate up to 120MHz RF bandwidth.

The device can be configured to use the 2G, 3G and 4G standards – including all TDD / FDD variants – and a host of additional standards, including WiFi.

Single chip MIMO (2×2)

To enable advanced networks to be created, the chip features a dual transceiver architecture. It integrates 12-bit ADCs and DACs, LNAs, filters and mixers to provide two transmit and receive paths, enabling a true single-chip (2×2) MIMO operation. The transceiver’s enhanced capability features, such as an on-chip microcontroller, further simplify its calibration and installation. Furthermore, its extensive on-chip DSP has been programmed to enhance functionality and performance.

Power

The device is fabricated using a low cost CMOS process and has been designed for the lowest possible power consumption.

The DSP supplements the analogue gain with digital control and is an important factor in reducing the overall power consumption. This allows the LMS7002M to operate from a single supply rail of 1.8V with individual blocks capable of being powered down for further power savings.

Interfaces

The LMS7002M has a standard serial port interface (SPI) for programming and includes provision for a full RF calibration. The device combines LNA, PA driver, RX/TX mixers, RX/TX filters, synthesizers, RX gain control, and TX power control with very few external components.

Design Tools

The chip is programmed by a serial bit stream and is designed using an open source configuration tool suite. The GUI provides access to all the parameters in each block. Designers can accept the defaults or change the control settings that are downloaded to the devices to meet their system requirements.

Package

The LMS7002M is packaged in a 11.5 x 11.5mm aQFN 261-pin package. It is available with the Universal Wireless Communications Toolkit (UWCT), which includes an evaluation board and associated software.

Functionality and cost

The LMS7002M FPRF transceiver can be used as a software-configured, fully-functional MIMO transceiver or to replace discrete ADC, DAC, DDS (direct digital synthesizer), AGC or RSSI (received signal strength indicator) devices. It has been priced aggressively to compete with these discrete components, allowing it to replace several individual chips.
