Xiegu G90

Description

The Xiegu G90 is a portable 20W HF amateur radio transceiver with an SDR architecture with built-in auto antenna tuner. The display unit and the radio can be separated. It is a new member of the Xiegu product family and the first model of the G series.

SDR Architecture: Power and Flexibility

One of the standout features of the G90 is its Software Defined Radio (SDR) architecture. With a 24-bit data size and a sampling rate of 48kHz, this transceiver delivers outstanding performance and a highly configurable user experience. The SDR platform allows for easy updates and modifications, ensuring that the G90 remains current with the latest technologies and standards in amateur radio.

Frequency Range and Modes

The Xiegu G90 covers the frequency range from 0.5 MHz to 30 MHz, encompassing all major HF amateur bands. It supports three working modes: Single Sideband (SSB), Continuous Wave (CW), and Amplitude Modulation (AM). This broad coverage and versatile mode selection make it an excellent choice for a wide range of operating activities, from casual chatting to more specialized pursuits like weak signal communication and contesting.

Display Unit: Detachable for Flexibility

One of the most innovative aspects of the G90 is its detachable display unit. The display can be separated from the host unit and connected via a VGA cable, providing unprecedented flexibility in how you set up your operating station. Whether you prefer to have the display mounted higher for better visibility or positioned differently for ergonomics, this feature ensures that your setup is optimized for comfort and efficiency.

Built-in Auto Antenna Tuner: Simplifying Operations

For many amateur radio operators, antenna setup can be a significant challenge. The G90 addresses this issue with its built-in high-performance auto antenna tuner. This feature automatically matches the transceiver to a wide range of antennas, eliminating the need for manual tuning and ensuring optimal performance regardless of the antenna used. Whether you’re using a dipole, vertical, or other types of antennas, the auto tuner adapts quickly to provide the best possible match, making operations smoother and more efficient.

User Interface and Features

The G90 features a 1.8-inch high-brightness color TFT LCD screen, which is clear and easy to read even in bright sunlight. The display shows essential information such as frequency, mode, signal strength, and other parameters. Additionally, the transceiver offers ±24 kHz bandwidth spectrum display and waterfall display, providing valuable visual feedback for monitoring activity on the bands.

The software-defined narrowband filter is particularly useful in CW mode, where a 300 Hz filter helps to suppress interference and improve readability of weak signals. This level of customization enhances the overall operating experience by allowing operators to tailor the transceiver’s performance to their specific needs.

Versatility and Expandability

The G90 offers diversified interfaces, including a baseband I/Q output that enables connection to external devices capable of handling baseband I/Q signals. This feature opens up a world of possibilities for advanced operations, such as interfacing with sound card-based or PC-based applications like the XDT1. This level of expandability ensures that the G90 can grow with your operating interests and technical capabilities.

Power Supply and Operating Conditions

The transceiver operates on a DC voltage range of 12 to 15V, with a standby current draw of 750mA at maximum and a transmitting current of up to 8A. It is designed to function optimally within a temperature range of 0°C to 55°C, making it suitable for both indoor and outdoor use, including emergency situations and portable operations.

Conclusion

The Xiegu G90 represents a significant advancement in amateur radio transceiver technology, offering a perfect blend of power, flexibility, and ease of use. Its SDR architecture, combined with the built-in auto antenna tuner and detachable display unit, sets new standards for performance and operator convenience. Whether you’re an experienced ham looking to upgrade your setup or a newcomer seeking a capable and versatile transceiver, the G90 is undoubtedly worth considering.

With its comprehensive feature set, robust construction, and excellent performance, the G90 is poised to become a favorite among amateur radio enthusiasts worldwide. Coupled with Xiegu’s 12-month manufacturer warranty, operators can have peace of mind knowing their investment is protected.
