The Magnetron MG5245 is a high-performance pulse magnetron, designed for demanding marine radar applications. Built with a rugged, compact structure, this magnetron ensures durability and consistent radar pulse generation, even in the harshest maritime environments. Operating at a fixed frequency of 9410 ± 30 MHz, it delivers a peak output power of 12.5 kW, providing reliable and precise radar performance essential for marine navigation and safety.
Featuring an indirectly heated cathode, the MG5245 is optimized for efficient operation with a heater voltage of 6.3 V and 0.5 A of current. The 60-second cathode pre-heating time ensures quick startup, even in fluctuating temperatures. Additionally, the MG5245 comes with an integrated magnet and a No. 16 waveguide output, ensuring both longevity and stable signal transmission. It is designed for flexible mounting positions, with a required minimum clearance of 25 mm from magnetic materials, allowing versatile installation options.
Natural cooling minimizes maintenance needs, while the IEC UBR100 coupler ensures compatibility with standard marine radar systems. With a maximum input capacitance of 8.0 pF and an excellent temperature coefficient of frequency, the MG5245 maintains stable performance across varying conditions. The magnetron undergoes rigorous testing to meet strict safety standards, providing protection against RF radiation and high-voltage exposure, making it a reliable and safe choice for maritime radar systems.
