ISM02 - Long Range, Low Power, sub-GHz RF Transceiver
ISM02A is a telemetry module based on the Semtech SX1262 RF transceiver. This module is widely used in LoRa and other sub-GHz wireless communication applications. It incorporates an RF switch (PE4259) to multiplex RX and TX on a single antenna, making it a compact solution for IoT and telemetry use cases.
Features
- RF Transceiver: SX1262
- More power-efficient compared to the SX127x series
- Additional features with a smaller footprint and fewer external components
- Operating frequency range: 150 MHz to 960 MHz
- Supports LoRa and (G)FSK modulation
- Maximum output power: +22 dBm
- Low power consumption: 4.2 mA in receive mode
- Complies with ETSI EN 300 220, FCC CFR 47 Part 15, and other global ISM band regulations
- RF Switch: PE4259 UltraCMOS RF switch
- Frequency range: 10 MHz – 3000 MHz
- Low insertion loss: 0.35 dB @ 1000 MHz
- High isolation: 30 dB @ 1000 MHz
- High ESD tolerance of 2 kV HBM
- Used to multiplex RX and TX on a single antenna
The module is typically used as a LoRa device and offers flexible wireless communication for various low-power, long-range applications.
Applications
- Remote sensors
- Agricultural sensors
- HAB/stratospheric balloon tracking and telemetry
- Remote control applications (UAVs, Robots)
