LD79A02K Datasheet PDF

NEC LD79A02K

LD79A02K is a complete integrated unit and can deliver an output power of 20 W over the range of 27.5 to 30.0 GHz with a gain of 40 dB. The TWT of RF section in the LD79A02K 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.

GENERAL DESCRIPTION

MPM stands for Microwave Power Module and is the solution introduced by NEC for a microwave power source with high efficiency and the most compact size. The MPM consists of a miniaturized traveling wave tube (TWT) and an electronic power conditioner (EPC). All the potential interface problems are taken care of by NEC and the user simply connects the MPM to his RF output and plugs in the DC supply. The LD79A02K is most suitable for a power amplifier in LMDS and Multimedia Satellite communication systems.

FEATURES

™ Light weight, Compact, and Efficient The TWT built in the MPM 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 correction of non-linear distortion of gain and phase generated in a TWT.
