Q-BRIDGE+ is a type of RF receiver, transmitter, and transceiver finished units. It is a highly integrated radio frequency (RF), microcontroller, and ARM Cortex-M4 based transceiver developed for high-speed, low-cost wireless communications building blocks.

Q-BRIDGE+ has a wide application field. It has a RF radio frequency receiver and transmitter with a data rate up to 7.2Mbps. It is also designed to support the GSM and CDMA standards, providing global coverage of frequency bands. With a power output of up to 32dBm, it can operate actively in non-line-of-sight (NLOS) environments. It is also capable of providing an analog-to-digital converter, digital-to-analog converter, dual-band antenna tuner filters, and other necessary hardware blocks, making it ideal for remote sensing, long range wireless communication or Internet of Things (IoT) applications.

Q-BRIDGE+ comes with many features and capabilities that make it suitable for various applications and markets. It supports up to 18 bands and delivers a data rate of up to 7.2 Mb/s in half-duplex mode. The radio is also interference rejection and spectral efficiency optimized to facilitate long-distance communication. It is also power efficient, with a peak power consumption of only 500 mW. Additionally, it can be configured to receive 16 channels of data and act as a base station.

The working principle of Q-BRIDGE+ is simple and effective. First, the radio receiver receives the RF signal from the air. Next, the transceiver processes the RF signal with its analog-to-digital converters and software-defined radio techniques to detect and decode the received signal. Then it processes the signal and sends the decoded data to the transceiver interface. Finally, the transceiver modulates the data and outputs the transmitted signal to the next node.

Q-BRIDGE+ is a powerful and cost-effective solution for wireless communication. It is particularly useful for remote sensing, long range wireless communication, and other IoT applications due to its extended frequency range, high-speed data rate, and low power consumption. By combining the necessary hardware components with a reliable transceiver, Q-BRIDGE+ costs much lower than a complete solution which includes separate receiver and transmitter modules.
