About the YJ1540
The YJ1540 is a continuous-wave (CW) magnetron manufactured by EEV / CPI. S-band CW magnetron at 2.45 GHz with 850 W continuous output, lower-power variant of the YJ1600 series for lighter industrial duty.
Key ratings of the YJ1540 include frequency 2.45 GHz, frequency band S-band, type CW (Continuous Wave), output power 850 W, anode voltage 3.8 kV and anode current 0.4 A.
Typical applications are industrial microwave heating, laboratory drying, plasma research and ISM-band equipment. Notable features: permanent magnet assembly, low anode current draw, compatible with YJ1600 sockets and long service life.
CW magnetrons convert DC anode power into a continuous microwave output and are the standard RF source for industrial microwave heating, drying, thawing and plasma systems in the 915 MHz and 2.45 GHz ISM bands. Anode voltage, filament supply and cooling must match the original tube, so replacements are normally selected by exact type number or a verified equivalent.
PartnerTubes supplies the YJ1540 worldwide from Groningen, the Netherlands — availability, lead time and price are confirmed per enquiry. Our team can help with equivalent and cross-reference types, sockets and accessories, and supply programmes for OEM and maintenance customers. Interchangeability must always be confirmed for the specific equipment.
