RF Evaluation and Development Kits, Boards, has a long history but is still widely used nowadays. The DVRFM631DF12N100 is one of the distinguished members of this family. It is a low cost system-on-chip (SoC) transceiver intended for applications like point-to-multipoint (PMP) systems, private land mobile radio (PLMR) systems, implantable medical device (IMD) systems etc. The DVRFM631DF12N100 can easily be integrated into a larger system and offers full system control, frequency hopping capabilities and most importantly, great wireless performance.

The DVRFM631DF12N100 is a highly integrated SoC designed for applications where high performance is important. It consists of a 12-bit Digital Signal Processor (DSP), Analog System Processor (ASP), and Power Management Units (PMUs). The DSP is responsible for channel adaptation, timing control, packet assembly and de-assembly, packet forwarding, and data transmission. The ASP is responsible for analog processing of the received signals and for calculating channel gain. The PMUs manage the power levels of the system and are also used to control the on-chip RF front-end. The system works with two antennae, the global antenna for receiving wireless signals from the air and the AP antenna for transmitting signals.

The DVRFM631DF12N100 has several features that make it the ideal choice for a range of application fields. It has integrated FSK (Frequency-Shift-Keying) and QAM (Quadrature-Amplitude-Modulation) modulation and demodulation capabilities, which allow for high speed and secure wireless communication. It also has an integrated error-correction engine and an embedded compact XOR-based encryption algorithm. This makes it suitable for applications where secure data transmission is critical. Furthermore, the chip also offers a wide range of frequency hopping capabilities, making it suitable for applications where frequency diversity is important.

The on-chip power-management capabilities of the DVRFM631DF12N100 enable the chip to be used in power-saving applications. Its power consumption ranges from <25mW in standby mode to up to 10W in Rx/Tx mode. Thus, the chip is suitable for use in battery-powered devices as well as in systems that require high power efficiency. The chip is also designed to be compatible with the Bluetooth Low Energy (BLE) protocol and so can be used in applications that require communication between BLE devices.

The working principle of the DVRFM631DF12N100 is fairly simple. It begins by receiving a wireless signal from the global antenna. This signal is then processed by the ASP and the DSP, which adapt the signal to the desired frequency and modulation parameters. The ASP calculates the channel gain and the PMUs adjust the power levels of the on-chip RF front-end. Finally, the signal is transmitted via the AP antenna.

In conclusion, the DVRFM631DF12N100 is a highly integrated SoC transceiver intended for applications such as PMP systems, PLMR systems and IMD systems. It offers a wide range of features,such as FSK and QAM modulation, integrated error-correction, power-management and compatibility with the Bluetooth Low Energy protocol. Furthermore, it offers a straightforward working principle, whereby wireless signals are transmitted and received via the global and AP antennae respectively, and are adapted to the desired frequency and modulation parameters. All these characteristics make the DVRFM631DF12N100 the ideal choice for a range of applications.
