Description

Westinghouse January 1, 1941 MAGNETRON TYPE 7795 Fixed Frequency 5 Watt Qutput Integral Magnets 4300 + 10 Megacycles 100% Amplitude Modulated 10 Watts with Duty Cycles The 7795 is a C band 5 watt CW magnetron. |t is designed for amplitude modulated communications, telemetering and relay systems requiring high average power with good bandwidth. In pulse code modulation systems peak powers up to 10 watts are available with duty cycles ranging to five watts average power. In amplitude modulated systems one hundred percent modulation ofa five watt carrier is permitted. With 100% modulation incidental FM is less than B megacycles. The rugged, light weight design of the 7795 permits use on girborne systems where shock and vibration are severe, The 7795 uses o multivaned anode structure and an oxide coated unipotential cathode. It contains a capacitive tuning element preset in the factory to 4300 * 10 megacycles. The integral magnets are enclosed in steel shells to shield the magnetron from s
