Description

The Eimac EM-1086 is a ruggedized, ceramic and metal packaged voltage- tunable magnetron capable of delivering a minimum output power of 15 watts into a 50 ohm termination over the frequency range of 940-1060 megacycles. Eimac's three terminal YVTM circuit has been used in this tube to give a more uniform output circuit with the added advantage of one-third more heat dissipating area extending out of the YTM envelope. The electron injection design incorporated in this magnetron minimizes
