10.7–11.5 GHz Block Up-Converter (BUC) – Ku-Band Satellite Uplink Device

The 10.7–11.5 GHz uplink power amplifier (BUC)​ is a key component in Ku-band satellite communication uplink systems. This frequency band belongs to the lower Ku-band uplink segment, and is characterized by stable spectrum availability, low interference risk, and compact equipment design. Its core applications are focused on satellite communication systems that prioritize reliability and portability, as outlined below:

---

一、Core Application Scope and Scenarios / 主要应用范围与场景

1. Portable / Emergency Satellite Communication Systems

适用场景 / Applicable Scenarios:​

• Emergency command communications at disaster sites such as earthquakes, floods, and landslides
• Temporary communication support in areas without terrestrial network coverage, such as remote mountainous regions, deserts, and oceans

核心价值 / Core Value:​

This BUC operates within the 10.7–11.5 GHz Ku-band, typically featuring small size, light weight (e.g., as light as 1.2 kg as previously mentioned), and low power consumption (max. 25 W). It can be integrated with a portable satellite antenna​ to form a “flyaway” or portable station, enabling rapid deployment​ and establishing an uplink for real-time transmission of voice, data, and video.

典型用户 / Typical Users:​

Emergency management departments, geological exploration teams, and field scientific research crews.

---

2. Maritime / Nearshore Small Vessel Communications

适用场景 / Applicable Scenarios:​

• Routine communication and navigation for small fishing boats, yachts, and nearshore work vessels
• Command and dispatch operations for coastal patrol boats

核心价值 / Core Value:​

The 10.7–11.5 GHz band​ experiences less interference from sea clutter, and the equipment offers strong resistance to salt spray and vibration (e.g., IP67-rated protection), ensuring stable operation in rough seas and high-humidity environments. It provides services such as broadband access and position reporting​ for crew members.

对比优势 / Advantage Comparison:​

Compared to higher-frequency Ku-band BUCs, this frequency range requires smaller antenna apertures, making it more suitable for installation on small vessels.

---

3. Small Fixed Satellite Ground Stations

适用场景 / Applicable Scenarios:​

• Broadband access for rural schools, clinics, and government offices in remote areas
• Private network data transmission for enterprise branch offices

核心价值 / Core Value:​

This frequency band benefits from relatively abundant spectrum resources and low interference levels, helping ensure long-term, stable uplink communication. It also offers lower equipment and operational costs compared to C-band systems, making it ideal for small-scale users and deployments.

---

4. UAV / Low-Altitude Aerial Vehicle Data Links

适用场景 / Applicable Scenarios:​

• Real-time transmission of high-definition imagery from mapping drones and inspection drones
• Remote control of small unmanned aerial platforms

核心价值 / Core Value:​

The bandwidth of this frequency range​ is sufficient to support high-definition video transmission, and the BUC provides a high linear gain (typically 55 dB), ensuring stable signal amplification even from weak intermediate frequency (IF) sources. This makes it well-suited for lightweight and low-power UAV applications.

---

5. Satellite News Gathering (SNG) Lightweight Equipment

适用场景 / Applicable Scenarios:​

• Outdoor live broadcasting by small news reporting teams
• Mobile reporting at sports events, concerts, and other live events

核心价值 / Core Value:​

This BUC can be paired with a backpack-mounted satellite antenna​ for “plug-and-play” deployment, meeting the time-sensitive demands of news reporting. It also features strong in-band spurious suppression (−60 dBc), minimizing potential interference with the satellite transponder.

---

二、Key Advantages of This Frequency Band / 该频段的核心优势

1. Low Interference Risk / 干扰风险低

The 10.7–11.5 GHz band is located far from the spectrum used by terrestrial 5G networks, reducing the likelihood of interference. As a result, there is no need for additional anti-jamming filters, which helps lower system complexity and cost.

---

2. Compact Equipment Design / 设备小型化

Compared to the C-band, the Ku-band has a shorter wavelength, allowing for smaller BUC and antenna sizes​ with reduced weight. This makes the system highly suitable for mobile and portable applications.

---

3. Moderate Link Loss / 链路损耗适中

Under the same antenna aperture conditions, the uplink path loss in the 10.7–11.5 GHz band is lower than that in higher Ku-band segments (e.g., 14–14.5 GHz). This results in better communication range and link stability.
