    Upconverter 1+1 is a high-reliability 70–90 MHz to L-band RF upconverter designed for satellite uplink systems, DVB-RCS hubs, SCPC networks, SNG vehicles and military communication platforms. Built around a dual hot-redundant architecture, it delivers continuous, uninterrupted operation even in the event of hardware failure. Its rugged aluminum chassis, modular interior blocks and long MTBF (>120,000 hours) make it suitable for stationary teleports, mobile broadcast trucks and field-deployed communication systems.

    Engineered with dual-conversion technology (70 MHz → 2400 MHz → L-band), the Upconverter 1+1 provides low phase noise, high spectral purity and stable conversion characteristics across the full 950–2150 MHz output range. Local front-panel control with LCD and LEDs ensures instant status visibility, while full Ethernet 10/100 remote management enables seamless integration into modern NMS and automated uplink infrastructures.

    ✅ High-reliability 1+1 redundant upconversion system

    The upconverter integrates two fully autonomous converter blocks operating in hot standby, ensuring uninterrupted RF output during equipment faults. Its redundancy supervisor monitors RF level, IF level, PLL lock and power supply status to trigger instant failover when required. Hot-swap capability allows technicians to replace individual converter modules without shutting down the chassis, providing exceptional uptime in mission-critical satellite networks.

    ✅ Advanced dual-conversion 70 MHz → 2400 MHz → L-band architecture

    The dual-conversion system significantly improves spectral purity while minimizing IMD3, spurious components and phase noise. A high-stability 10 MHz reference oscillator (0.01 ppm) ensures accurate and predictable output frequencies across 950–2150 MHz. The converter maintains excellent linearity and stable gain characteristics, ensuring compatibility with DVB-S/S2, DVB-RCS, SCPC and other satellite modulation schemes.

    ✅ Comprehensive local and remote management with Ethernet control

    Front-panel LCD, LEDs and keypad offer full local configuration of gain, attenuation, switching logic and monitoring functions. Ethernet remote control enables operators to manage the converter from teleports, NOCs or automated uplink controllers. Detailed alarm reporting improves fault diagnosis and ensures quick maintenance intervention. The system provides granular gain adjustment up to 50 dB in 1 dB steps, enabling fine IF-to-RF power optimization for any uplink topology.

    🛠️ The Upconverter 1+1 provides operators with a fault-tolerant RF conversion chain capable of meeting stringent broadcast, VSAT and tactical communication requirements. Its automatic switchover system detects failures in RF levels, PLL lock, reference stability or power supply performance, ensuring that the backup module takes over instantly. Hot-swappable converter blocks and PSU modules further minimize downtime, enabling rapid on-site maintenance without interrupting L-band transmission.

    🛒 With its compact 1RU rackmount chassis, extremely low phase-noise oscillator and wide gain adjustment range (50 dB), the Upconverter 1+1 offers both performance and flexibility. It is ideal for integration into multi-carrier uplinks, mobile SNG systems, military communication shelters and DVB-RCS gateways that require continuous, stable L-band output under all operational conditions.
