JRC M1568BS Magnetron (X‑Band Radar)
Overview
The JRC M1568BS magnetron is a high-performance X‑band component engineered for marine radar systems. Delivering a robust 25 kW peak output within a fixed frequency range of 9380–9440 MHz, it ensures persistent and reliable radar signal generation essential for safe and accurate vessel navigation.
Key Features & Benefits
-
Powerful Radar Output
Delivers a peak output power of 25 kW, suitable for demanding radar applications including marine and weather systems. -
Reliable Frequency Range
Operates consistently within the fixed X‑band frequency spectrum of 9380–9440 MHz, optimizing radar performance. -
Precision Engineering
Built to exacting standards with features that include a peak anode voltage of around 8 kV, a peak anode current of 6–10 A, and duty cycles/pulse durations between 0.001 and 1.2 μs. -
Compact & Durable Design
Lightweight at approximately 0.7 kg, and designed for both forced-air and natural cooling methods—ideal for high-use maritime environments. RoHS compliant for environmental safety. -
Built for Longevity
Engineered to withstand high operational stress, including elevated anode temperatures (up to 110 °C) and fast voltage rise rates (up to 100 kV/μs). -
Standard Interfaces
Configured for direct insertion into waveguide systems (WR90) with compatible RF flanges (UG‑135/U equivalent) and standard lead wire power interfacing.
Suggested Maintenance Advice
If your radar’s echo reception weakens or the tune bar performance degrades, it’s likely time to replace the magnetron—especially after approximately 5,000 hours of transmission time. Technicians can typically perform replacement along with cleaning or changing the radar carbon brushes.
