Glossary & Supplementary Notes

Mini BUC: Miniature Block Up-Converter, featuring a smaller size and lighter weight compared to conventional BUCs, ideal for portable applications.
dBc: Decibels relative to the carrier power, a unit used to measure the intensity of spurious signals and noise relative to the carrier signal. A lower value indicates lower interference or noise.
IP67: Ingress protection rating standard. The digit 6 means complete protection against dust ingress; the digit 7 means protection against the harmful effects of immersion in water up to 1 meter deep for 30 minutes without affecting device operation.

I. Core Application Scenarios

1. Satellite on the Move (SOTM) for Small Mobile Platforms

Applicable Carriers: Small vehicle-mounted satellite stations, UAV-borne communication systems, individual soldier backpack satellite terminals.

Core Value: The 13.00–13.25 GHz band is a dedicated mobile uplink frequency assigned by some international satellites, featuring low interference and stable links. When paired with miniature flat-panel antennas or phased array antennas, it enables real-time broadband communication during vehicle movement or UAV flight, meeting the data transmission needs of emergency command, border patrol, and UAV surveying and mapping.

Adaptation Advantages: The lightweight 0.7 kg design significantly reduces the load pressure of mobile platforms. The IP67 rating can withstand vibration, rain, sand, and dust in vehicle-mounted/airborne environments.

2. Rapid Deployment of Emergency Portable Satellite Stations

Applicable Scenarios: Temporary communication support at disaster sites such as earthquakes, flash floods, and wildfires; field operation communications in remote mountainous areas, deserts, and islands (e.g., geological exploration, scientific expeditions).

Core Value: It can be integrated with portable manual antenna pointing systems to form a backpack satellite station, which can be carried and deployed by a single person. The 15–24 V wide voltage input is compatible with battery power supply, enabling rapid establishment of uplink communication without grid power. It supports two-way transmission of voice, video, and data, solving the problem of "communication isolation" when ground communication is interrupted.

3. Maritime Communications for Small Vessels

Applicable Carriers: Small fishing boats, yachts, speedboats, and other coastal operating or recreational vessels.

Core Value: The 13.00–13.25 GHz band is less affected by electromagnetic interference from the sea surface. With strong salt spray and high humidity resistance (IP67), the device can operate stably in the bumpy, high-salt-spray marine environment. It provides satellite broadband access, position reporting, and emergency distress functions for crew members. Compared with traditional maritime communication equipment, it has lower cost and smaller size, making it suitable for installation on small vessels.

4. UAV Satellite Data Links for Low-Altitude Operations

Applicable Scenarios: Long-range control and HD image transmission of long-endurance UAVs (e.g., power line inspection, forest fire prevention, agricultural plant protection).

Core Value: With a linear gain of 55 dB and in-band spurious suppression of -60 dBc, it ensures distortion-free amplification and transmission of weak intermediate frequency signals, meeting the lightweight and low-power requirements of UAVs. The uplink in the 13.00–13.25 GHz band can break through the distance limitation of ground data transmission, enabling beyond-visual-line-of-sight (BVLOS) stable communication over 100 km.

5. Small Fixed Satellite Earth Stations

Applicable Scenarios: Broadband access for rural schools, clinics, and small base stations in remote areas; private network data transmission for enterprise branches and security monitoring points.

Core Value: The frequency band has relatively abundant spectrum resources and low interference, ensuring long-term stable uplink communication. The compact size allows wall-mounted installation or integration with small antenna mounts, resulting in low operation and maintenance costs, which is suitable for deployment by small-scale users.

II. Core Advantages for Scenario Adaptation

Miniaturized Design: The 0.7 kg weight and compact dimensions make it one of the optimal choices for portable and mobile scenarios, much lighter than conventional BUCs of the same power level.
Low Power Consumption & Wide Voltage Compatibility: With a maximum power consumption of 20 W and 15–24 VDC input, it is compatible with multiple power supply modes such as batteries and vehicle-mounted power supplies, suitable for off-grid field environments.
High Protection & Wide Temperature Operation: The IP67 protection rating and wide temperature range (-40℃ to 55℃) enable adaptation to harsh environments with high temperature, low temperature, high humidity, and sand dust.
Low Spurious Emissions & Low Phase Noise: The in-band spurious suppression of -60 dBc and excellent phase noise performance prevent interference to satellite transponders and ensure high-quality communication links.
