HIGH POWER TRAVELING WAVE TUBE

DATA S H E E T MICROWAVE POWER MODULE FOR GROUND TERMINALS LD79U04K 14 GHz, 40 W CW, LIGHT WEIGHT, COMPACT, EFFICIENT GENERAL DESCRIPTION NEC Microwave Power Module (MPM) LD79U04K is a microwave power device in which a traveling wave tube (TWT) and an electric power conditioner (EPC) are combined, so that both components can accomplish each full performance. LD79U04K delivers an output power of 40 W over the range of 13.75 to 14.5 GHz with a gain of 25 dB. The TWT in the LD79U04K has been designed and developed upon the NEC's advanced technology and enormous experience on a number of TWTs used in satellite ground terminals and terrestrial microwave links. The very small and light weight EPC designed with sophisticated and experienced circuit technology ensures higher reliability, reduced maintenance costs and improved technical performance. The LD79U04K is most suitable for a power amplifier in digital communication systems. A configuration of separated TWT and EPC can offer superior flexibility of design for high power section of transmitters. FEATURES ™ Light weight, Compact, and Efficient The TWT has a dual-depressed collector and is designed to operate at high efficiency across the power output range. The EPC features state-of-the-art techniques to optimize size and efficiency and the combination results in a unit significantly smaller and with less power consumption than a comparable solid state amplifier. ™ Low Distortion NEC has developed techniques for the correcti.
