RF Evaluation and Development Kits, Boards include products such as the EVB71112B-868-FSK-C, which provides engineers with an ideal solution for developing Frequency Shift Keying (FSK) based radio frequency (RF) applications. The EVB71112B-868-FSK-C module has two parts, the Evaluation board and the radio-frequency (RF) module attached to it.

EVB71112B-868-FSK-C Application Field

The EVB71112B-868-FSK-C is mainly used for the development of wireless data transmission systems, such as wireless alarms, remote control systems, wireless sensors, telecommunication networks, vehicle location systems and others. The module can be used in both point-to-point and point-to-multipoint applications. It is particularly suitable for applications that require long range wireless transmission, such as environment monitoring, asset tracking and telemetry. The EVB71112B-868-FSK-C can also be used in the433 MHz ISM band.$ (Industrial, Scientific and Medical) for industrial applications. The ISM band is a license-free band that can be used by anyone, without needing to register with government authorities.

EVB71112B-868-FSK-C Working Principle

The main working principle of the EVB71112B-868-FSK-C is the RF Modulation. The module uses a frequency-shift-keying (FSK) modulation technique to ensure long range wireless communication. In this technique, data is encoded in binary, with "0"s and "1"s represented by two separate frequencies. The module has a modulation frequency of 145 KHz with a maximum data rate of 1 Kbps. The module also employs Reed-Solomon forward error correction to reduce errors in the transmitted data.

The onboard power amplifier helps to increase the range of the radio signals, and the output power can be set up to 20 dBm. The high linearity of the EVB71112B-868-FSK-C ensures improved signal quality. The module also has selectable output power options, which help to conserve battery life. The module can be set to output up to 5 Watts of power, which is helpful in outdoor applications such as asset tracking.

The EVB71112B-868-FSK-C is also equipped with on-chip voltage regulation circuitry to ensure it runs at the correct operating voltage. This helps to conserve battery life and reduces the need for bulky batteries. The module is also designed to be small, light weight and highly integrated, which makes it ideal for small form factor applications.
