This paper presents a new approach to design MMIC LNAs. The proposed method allows to filter the out-of-band LNA gain and ensures the best compromise between input and noise matching in the Ka band (27-31 GHz) example. Because of these very strong constraints a rigorous method has been planned for selecting the best transistor whatever the MMIC technology. Then, in order to relax front-end selective...
This paper describes the design of a GaAs monolithic high power amplifier at Ku band. The chip delivers about 40 dBm of saturated output power, in CW operating conditions, at 11.7 GHz central frequency, with 17% of bandwidth. The saturated power gain is 12.4 dB with 2 dB gain flatness across the application bandwidth while the chip power added efficiency is estimated between 33% to 47%. The amplifier...
This paper presents a new methodology for reducing power consumption of power amplifiers from low level to high level RF power with minimal amplitude and phase variations. The study also highlights the important design considerations to achieve a good efficiency and excellent amplitude and phase tracking among the SSPAs.Using this methodology a flexible S band SSPA has been designed for the new generation...
