RF accessories provide some of the key antecedents for efficient communication over radio frequency (RF) channels. One such accessory is the DG-EXT-200-UU-B, which add additional capabilities to the HF and VHF radio bands. The accessory plays an important role in providing increased data throughput, as well as more reliable data transmission. In this article, we will discuss the application field and working principle of the DG-EXT-200-UU-B.

Application field: The DG-EXT-200-UU-B is typically used for long-range communications between stations or for data transmission over greater distances. It is crafted with form factors that are suitable for use in wide variety of environments. Furthermore, the accessory is supplied with an integrated, 32 kHz real-time clock, which offers excellent frequency stability. The device also offers transmit and receiving capabilities for HF, VHF and UHF applications, such as aircraft communications or ship-to-ship communication.

In addition, the DG-EXT-200-UU-B is built with sophisticated digital signal processing techniques, allowing operators to use the device’s large bandwidth efficiently. The accessory is highly robust and can be used in harsh conditions. Moreover, the antenna interface is housed in a waterproofed, metallic enclosure, which ensures reliable operation in all climates. Other features of the antenna include adjustable linear attenuators, frequency selectivity, wide dynamic range and adjustable signal-to-noise ratio (SNR).

Working principle:The DG-EXT-200-UU-B is based on a digigram receiver concept, which makes use of the properties of frequency-division multiplex (FDM) systems. The frequency range of operation is typically 1.5 to 30 MHz and the device is powered by a 12V DC supply. This accessory is equipped with a superheterodyne receiver that employs direct conversion FDM receivers to receive and amplify signals. Additionally, the antenna interface features an adjustable sensitivity setting that can be tuned to ensure efficient operation. In order to transmit signals, the accessory is designed with a wide-band transmitted that offers linear modulation bandwidths, low phase distortion and robust transmission. The transmitter has an RF gain adjustable from -3dB to + 10dB and output power adjustable from 1mW to 10W. The transmitter also supports multiple protocols such as Frequency-Division Multiple Access (FDMA) and Time Division Multiple Access (TDMA). The device also features a suite of digital signal processing functions for superior performance.

In summary, the DG-EXT-200-UU-B is a versatile RF accessory that is designed for efficient long-range communications and data transmission. The device is crafted with form factors suitable for use in wide range of environments and is equipped with sophisticated digital signal processing techniques. The accessory is powered by a 12V DC supply and has adjustable sensitivity setting,linear attenuators, wide frequency range, adjustable signal-to-noise ration and wide transmission capabilities. Overall, the DG-EXT-200-UU-B is a rugged and efficient accessory for HF, VHF and UHF applications.
