Milestones
This is a modular design to make it easy for engineers to integrate the Station G3 into their designs. The Lora module BQ35LORA900V1M for the Station G3 features a new LNA design with dynamic gain control and impedance matching. Compared to Station G2, Station G3 achieves better RX performance in environments with higher RF noise levels. For the LoRa Power Amplifier, Station G3 offers four adjustable RF output settings, enabling it to better adapt to application scenarios with varying power consumption requirements.
Station G2 is an upgraded design of Station G1, using the latest ESP32 S3 MCU. As an RF research project, Station G2 also brings key updates in RF. The primary RF design goal of Station G2 is to improve the Lora receiving sensitivity by about 4dB based on a dedicated Ultra-Low Noise Figure LNA. And to increase the transmit power and improve Signal to Noise ratio of short data packets by designing the Fast-Transient DC-DC for 35dBm Lora PA. For Lora Power Amplifier, the 1 dB Compression Point (P1dB) is 35 dBm (3.16 W), and the maximum RF output power is 36.5 dBm (4.46 W) for US915 and 37 dBm (5 W) for EU868.
The primary design goal of the Nano G2 Ultra is to reduce power consumption and improve battery life by using the low power MCU NRF52840 and optimizing the power related designs. The typical battery life is optimized to be about 5 days. Nano G2 Ultra and Nano G1 Explorer have exactly the same Lora front-end circuit design and internal wideband Lora antenna, which supports frequencies from 815 Mhz to 940 Mhz. The wideband antenna, combined with an optimized wideband Lora RF frontend circuit, enables the Nano G2 Ultra to work with the majority of regions’ LoRa frequency bands around the world without the need for antenna changes.
Nano G1 Explorer features a new internal wideband Lora antenna, which supports frequencies from 815 Mhz to 940 Mhz. The wideband antenna, combined with an optimized wideband Lora RF frontend circuit, enables Nano G1 Explorer to work with the majority of regions’ LoRa frequency bands around the world without the need for antenna changes. Nano G1 also takes into account the potential effect of the human body on its antenna performance, ensuring optimal RF performance even when carried in a pocket.
Station G1 is a compact Lora device with 35dBm high power PA, rugged SMA Antenna Socket, rich external IO interface, wide input voltage range (8VDC-20VDC). Fixed-location base stations and vehicle-mounted base stations are typical application scenarios for this series.
The Nano G1 is a compact Lora device with high efficiency internal compact Lora PCB Antenna, ultra-low noise figure amplifier and internal GPS module. This series aims to balance the RF performance, size, rugged construction and power consumption.
