The MPA version is available for both Analog and Digital Direct Synthesis (DDS) version for a higher efficiency line of transmitters.
DB Elettronica Telecomunicazioni will bring its PFG NEXT/MPA line of medium- and highpower FM transmitters to CABSAT 2023. Its modular hotplug power amplifiers were designed by DB Elettronica R&D with an intelligent system of paralleled hot-plug power supply units. These have been designed to keep service and maintenance simple while ensuring redundancy.
The toolless instant installation from the front panel makes the transmitters ideal for critical environment systems where no downtime can be tolerated. Lightweight PA modules simplify the shipment, reducing the cost of delivering spares and allowing easier maintenance with a single person involved, thereby reducing maintenance costs and spare parts. No user adjustments are requested, and they are fully interchangeable in PFG NEXT/MPA transmitters.
Each unit has a software-controlled automatic current balancing system (ACS) for perfect load distribution and best power supply operating conditions. With multiple power supplies installed in the transmitter, the system always works without any current overload even in the case of failure of one power supply, also guaranteeing a perfect balance of load for three-phase systems.
Speaking about the product, Guglielmo Feliziani, CEO of DB Elettronica Telecomunicazioni, said: “We are proud to introduce in the market our new line of amplifiers: KFG NEXT MPA FOR FM BROADCASTING. The KFG NEXT MPA- MODULAR POWER AMPLIFIERS with hot-plug power supply units and hot plug multiple RF modules bring several major benefits to FM transmitters: increased efficiency; increased redundancy; easier and less expensive maintenance¸ increased reliability¸ energy saving. The Mpa Amplifiers are built with inside the latest and most advanced Idmos transistors, bringing even higher the efficiency of KFG NEXT and taking them to a 75% typically overall.”
