RF Evaluation and Development Kits, Boards produce necessary interface and capabilities to facilitate development of Radio Frequency (RF) circuits for various technologies. The OM7623/BFU725F/2400,598 is an evaluation board featuring useful components which facilitate to design, build and test RF circuits.

Application Field: This board supports the Single-Carrier Wideband Wireless System Standard, which uses Orthogonal Frequency Division Multiplexing (OFDM) waveform in the band from 2400 – 2483.5 MHz. It is ideal for wideband communication systems, such as Wi-Fi (IEEE 802.11) and HiperLAN.

Working Principle: The OM7623/BFU725F/2400,598 uses Direct Sequence Spread Spectrum (DSSS) technology, which is a combination of transmission and frequency-hopping techniques that use a broad frequency spectrum spread in a pre-determined manner. The basic structure of the OFDM system is composed of multiple narrowband carriers with a common spreading code. When multiple OFDM carriers are transmitted, it utilizes a time varying channels by sweeping up and down a wide frequency band. This sweep facilitates the transmission and reception of data, and the most common techniques for this are four separate noise shaping processes. These processes reduce the total power in the spectrum by shifting powers from one frequency to another, thus reducing the power-bandwidth ratio by a factor of four.

The OM7623/BFU725F/2400, 598 evaluation board provides powerful features such as OFDM Quadrature Modulator, ultra low power consumption, fast time setup and data rate that makes it the ideal choice for integration into a variety of wireless applications. It also offers ETSI-defined data rates for synchronization, as well as time and frequency hopping and provides an open platform for testing and developing transmitters and receivers.

The OM7623/BFU725F/2400,598 board consists of a Quadrature Modulator for the transmission of Wi-Fi class data, a Spread Spectrum Apparatus for sensing received signals, a Pre-Distortion Analyzer, and a Digital Receive Signal Analyzer (RSA). The Pre-Distortion Analyzer is an advanced multi-frequency analyzer that measures the amplitude and phase of the signal-to-interference ratio for nonlinear distortions caused by interference in the downlink signal. The RSA measures the signal-to-interference ratio and QAM symbol-noise powers for the received signal enabling users to assess the performance of a spread spectrum receiver.

In addition, the OM7623/BFU725F/2400,598 board is powered by a low power Oki-Processor, making it suitable for small- and medium-scale applications. The board is fully programmable and configifiable, allowing users to set parameters for the radio frequency communication. The data rate can be adjusted up to a maximum of 24 Mbps which makes it suitable for applications with high data rate requirements.

In conclusion, the OM7623/BFU725F/2400,598 evaluation board is an efficient and reliable board suitable for radio frequency communication. It offers advanced features such as data rate, time and frequency hopping, and low power consumption, making it an ideal choice for a variety of applications.
