RF Solutions LAMBDA-9S 915MHz LoRa Transceiver Module SMT

RF Solutions LAMBDA-9S 915MHz LoRa Transceiver Module is an FCC-certified 915 MHz RF transceiver module supplied in a compact SMT package, offering long-range spread spectrum communication built around the Semtech SX1272 LoRa chipset.

Overview

The module is designed for demanding wireless applications where reliability and range are critical. It uses LoRa spread spectrum modulation to enable ultra-long-range communication with strong immunity to interference while maintaining minimal current consumption.

The module is supplied as a complete RF solution. It integrates a crystal, an RF changeover switch, an impedance matching network and an optimised PCB track layout. This integration provides a simple digital interface and allows a direct antenna connection, which helps streamline the design process. Programming and control are carried out via a standard SPI interface.

Key Features

• Range: communication links of up to 16 km under ideal conditions
• Power amplifier: +14 dBm high-efficiency output with integral impedance matching network
• Receiver sensitivity: down to -130 dBm
• Link budget: maximum 157 dB
• RF output: constant output of up to +20 dBm (100 mW)
• Modulation: FSK, GFSK, MSK, GMSK, LoRa and OOK, with a programmable bit rate of up to 300 Kbps
• Integrated functions: built-in bit synchroniser for clock recovery, temperature sensor and low-battery indicator
• Intelligent operation: automatic RF signal sensing, Channel Activity Detection (CAD) and Automatic Frequency Control (AFC)
