Product Description

The LoRaWAN 86x/9xx Expansion card (CG2132) adds the LoRa functionality to the gateway of the CloudGate family from Option. The card is built around the Semtech SX1302 microcontroller with integrated LoRa FEM SKY66420 (Skyworks). It is a dual-band LoRa card with 868 MHz and 915 MHz available bands. Digital processing of the signal is performed by the microcontroller (SX1302), while conversion from/to RF signal is done in the LoRa Transceivers (SX1250). The Front-End module (FEM)(SKY66420) includes the Tx/Rx switch, power amplifier and low-noise amplifier (LNA) for the receiver. The card is using an external Tx/Rx antenna attached via an SMA RP connector. The expansion card is attached to the host device via a Card Edge Connector with 36 pins. Serial Peripheral Interface (SPI) is used for communication between the microcontroller and the host device (gateway). In addition, identification of the LoRaWAN 86x/9xx Expansion Card by the host device is provided via erasable programmable read- only memory (EPROM) which is using I2C interface to communicate over the Card Edge Connector.

The initial power line of 3.4 V gets split into two lines:

• 3.4 V for the radio components
• via a DC/DC converter 1.2 V line for the microcontroller (core line).

There is a condition for power delivery according to which the core power needs to be provided first to the SX1302 before the radio components will receive the required 3.4 V. The temperature-compensated crystal oscillator (TCXO) is powered by 3.4 V and provides the 32 MHz clock signal to both transceivers (SX1250) compensating for temperature-based frequency drift.
