Abstract

A magnetron device in which the wire's diameter of coils for the core type inductor and the air-core type inductor is 1.0 to 1.4 mm, and the cross sectional area of the magnetic core is 5 to 16 mm2, the number of turns of the coil for the air-core type inductor being 55 < 2 ⁢ π ⁢ D + A / 2 ⁢ T ≤ 90 ,
Figure imga0001
for the choke coil (35) accommodated in the filter box (31) disposed so as to cover the cathode terminal (33) of the magnetron tube body (10), which is comprised of the core type inductor (36) having the magnetic core (36a) and the air-core type inductor (37), and both thereof being serially connected together, where A (mm) is the wire's diameter of the coil, and D (mm) is the diameter of the magnetic core.
