Lime Microsystems' LMS7002M RF transceiver combines low-noise amplifiers (RXLNA), TX power amplifier divers (TXPAD), receiver/transmitter (RX/TX) mixers, RX/TX filters, synthesizers, RX gain control, TX power control, the analog-to-digital and digital-to-analog converters (ADC/DACs), and is designed to require very few external components.
The device uses state-of-the-art transceiver design on CMOS technology to significantly reduce cost and power consumption. It integrates a dual-transceiver architecture to support 2 x 2 MIMO along with significant digital functionality on the chip. The LMS7002M can run on any mobile communications standard (including Wi-Fi and all 2G, 3G, and 4G variants) and on any commonly used mobile communications frequency (both licensed and unlicensed), making it ideal for any wireless communication and broadband project.
The EVB7 module is a high-speed wireless communication module, based on the LMS7002M fully programmable RF transceiver. It is designed to support 2G, 3G, and 4G/LTE radio systems with time-division duplex (TDD) and frequency-division duplex (FDD) applications, M2M, and software-defined radios. The wireless communication module covers the frequency range of 100 kHz to 3.8 GHz, including licensed and unlicensed bands. The channel bandwidth is programmable from less than 100 kHz to 108 MHz through a combination of analog and digital filtering via the easy-to-use GUI software.
