SUPER LOW-NOISE HJ-FET FOR BROADCASTING SATELLITE SERVICE

摘要

In step with the rapid growth of DBS(Direct Broadcasting Satellite Service)market, demands for high-performance in the DBS converter have been increasing. Therefore, the development of high-performance and high productivity FETs have been urgently required. NEC has developed a new super low-noise HJ-FET (NE3210S01) with high-gain characteristic for the frontend application of DBS converters. This HJ-FET shows excellent noise and gain performance at 12GHz (NF=0.35dB typ., Ga=13.5dB typ).and it is very suitable to realize super low-noise and high-gain performance in DBS converters. This paper describes the characteristics of NE3210S01 and application systems.
