1.2 GHz Mini-Bridger Amplifier

For cable operators seeking backward compatibility and network scalability, the MB120 MiniBridger Amplifier delivers DOCSIS 3.1 performance while supporting legacy 750 MHz, 870 MHz, and 1 GHz systems. Its modular design ensures flexible deployment, low CAPEX, and reliable service to subscribers.

Equipped with Gallium Nitride (GaN) RF outputs, modular electronics, plug-in equalizers, and pluggable diplex filters, the MB120 optimizes frequency splits and system performance while maintaining compatibility with existing housings. Analog and QAM Automatic Level Control ensures stable gain, with selectable Manual or Thermal Gain Control modes for operational flexibility.

Features:

• 1.2 GHz downstream / up to 204 MHz upstream
• Modular RF electronics with upgradable frequency splits
• Enhanced gain for ≥ 750 MHz drop-in upgrades
• Compatible with legacy housings (optional MB‑15AII‑KIT)
• Plug-in equalizers & cable simulators for optimized performance
• Analog & QAM Automatic Level Control with gain hold
• Selectable RF ports and return path equalizers
• Operational: ‑40 °C to +60 °C, low noise & distortion
