Overview

The LMS7002M is a highly integrated, field-programmable radio frequency (FPRF) transceiver designed for next-generation wireless communications. It covers a continuous frequency range from 100kHz to 3.8GHz and incorporates dual transceivers with integrated microcontrollers, DSP, and SRAM to support a wide variety of cellular and broadband standards.

Why Choose This Part

The device offers massive integration by combining dual TRX chains, fractional-N synthesizers, and ADCs/DACs into a single 11.5mm x 11.5mm aQFN package. Its wide tuning range from 100kHz to 3.8GHz eliminates the need for multiple discrete RF front-ends, while the low 1.1V to 1.89V supply voltage optimizes power efficiency for portable designs.

Applications

Software Defined Radio (SDR)
Ideal for flexible radio platforms requiring wide frequency coverage and high bandwidth for rapid prototyping.
Cellular Infrastructure
Supports multi-standard base stations including GSM, WCDMA, HSPA, and LTE across various frequency bands.
Unmanned Aerial Vehicles (UAVs)
Provides long-range, frequency-agile communication links for telemetry and payload data transmission.
Whitespace Communications
Enables cognitive radio applications and WiFi operation within unutilized TV broadcast spectrum.
