RF Evaluation and Development Kits, Boards are essential for the development and evaluation of current or future applications utilizing radio frequency technology. This article discusses the application field and working principle of one of such devices – the HFR-SW1000-E.The HFR-SW1000-E is a frequency synthesizer module focused primarily on WCDMA and LTE operation. It is capable of working in several different frequency bands, including Cellular (2G/3G/4G), IoT, APT/PCS1900, and 5G, due to its wide coverage. The module, in addition to providing digital control, features a high-frequency signal analog output in the range of 400 MHz to 4 GHz.As for application fields, the HFR-SW1000-E is perfect for RF communication products. It can be used for wireless communication module prototyping and testing, helping to quickly build prototypes for developing and testing wireless communication projects, such as cell phones, base stations, drones, etc. This module is also capable of supporting antenna evaluation and integration, making it ideal for antenna design or related wireless communication sampling experiments. Due to its excellent performance and small size, the HFR-SW1000-E is ideal for space exploration and research. The module is also helpful in terms of RF frequency hopping, a technology used for radar communications. The module is equipped with digital step control, meaning the user can choose any given frequency without needing to search for it, making it suitable for use in the field of frequency hopping.In terms of working principle, the HFR-SW1000-E is based on synthesizer signal source technology and utilizes a direct digital synthesizer (DDS) chip to quickly and accurately generate any given frequency. The module uses digital frequency division technology to divide the reference clock frequency into a series of discrete steps. The user can then input a detailed frequency value. The module’s digital signal processing (DSP) technique then adjusts the signal while maintaining its frequency stability, meaning that the output signal frequency will remain constant in spite of power supply fluctuations or other transient phenomena. Additionally, it features short signal processing time, accommodating thousands of different frequencies per second, making it suitable for use in frequency hopping. Overall, the HFR-SW1000-E is an ideal device for both developers and engineers in the field of wireless communication. Not only can it be used for RF communication products, space exploration, research and development, and frequency hopping, but its excellency and performance is guaranteed due to its digital frequency division and signal stabilizing techniques.
