RF transceiver modules are among the most versatile and popular wireless communication solutions available in the market today. Using an RF transceiver module allows developers to quickly and easily integrate wireless communication into their applications. The BT840 is a high-speed radio transceiver module from CEL, Inc. that provides an advanced solution for wireless communication. It is specifically designed for long range applications where reliable data with consistent output and low power consumption is required.

The BT840 is designed to support the 2.4GHz to 2.5GHz frequency band using the industrial, scientific, and medical (ISM) band. It utilizes an on-chip CMOS amplifier and radio frequency (RF) circuit, which allows it to be used with low-cost circuits for the power amplifier. This device also uses a differential phase-shift keying (DPSK) spread-spectrum modulation technique for communication, allowing it to achieve a maximum payload rate of 600 Kbps. The BT840 also contains an integrated temperature sensor which can be used for self-monitoring and a range of additional functions for optionally extending the temperature range.

The BT840 offers several advantages over other RF transceiver modules. It has an output power of up to +20dBm, which provides up to 10 times the range of most other modules, and it also provides low power consumption with just 80 to 145 mW transmitting power. It also supports standard spread-spectrum modulation techniques, which are widely accepted in the industry, as well as two-way communication and various frequency hopping options.

The BT840 utilizes an advanced radio architecture for enhanced performance and has integrated support for spread-spectrum processing. The device contains an on-chip amplifier architecture and spread-spectrum processing circuitry, which allows it to be used efficiently and with improved quality of communication compared to traditional radio designs. This architecture also provides built-in layer 1 and layer 2 security features, which are essential for secure communication.

The BT840 is versatile and able to be configured for various applications. The main application fields of this transceiver module are in long-range wireless communication. It can be used in various systems such as mesh networks, home automation, asset tracking, industrial automation, security monitoring systems, and robotics. GT also makes the device suitable for audio streaming applications, voice over IP, wireless audio transmission, digital image, and video transmission.

In addition to its application fields, the BT840 also boasts a robust construction for added reliability. It has a low-noise, low-power architecture that is compatible with most mobile platforms. This RF transceiver module also features wide input voltage range, low current consumption, and low power consumption when transmitting. The BT840 also contains an on-chip temperature sensor, which helps the device self-monitor for temperature changes, improved robustness, and shorter shut down time.

The working principle of the BT840 is quite simple. When transmitting, it generates a radio frequency (RF) signal using its on-chip CMOS amplifier and RF circuit. This signal is then modulated using different modulation techniques to achieve the desired data rate or payload. Once the signal is received by the receiver, the data is demodulated and decoded, so that it can be used for further processing.

The BT840 from CEL is an advanced RF transceiver module that provides reliable, low-power communication for long-range applications. This versatile device can be used in many different applications such as mesh networks, home automation, asset tracking, industrial automation, security monitoring systems, and robotics. It also offers easy configuration, wide input voltage range, low current consumption, robust construction, and an integrated temperature sensor. The BT840 offers enhanced performance and improved security through its advanced radio architecture and is an ideal choice for wireless communication applications.
