Description

Fixed frequency pulse magnetrons differing only in cold impedance and heater/cathode cormections. M5196A and M5196B are direct replacements for the MBO9A and MBJ9B respectively, being mechanically and electrically interchangeable but tested to more stringent alectrical specifications. Under most conditions they have a longer operating life. Frequency retige . . . . . ., L. . 945t 89475 MHz Typica! peak output power . . . . . . . . . . 4.0 kW Magnet . . . . . . . . . .
