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...
A very high efficient, low distortion C-band power amplifier using a linear and non-linear models of the PHEMT devices has been developed. Single stage amplifier fabricated with 4??18mm gate width PHEMT devices exhibits a power output of 44 dBm at 2dB of gain compression, a linear gain of 11.5dB and an associated PAE from 50% to 52% in the frequency range of 3.6-3.9GHz. These excellent results are...
A very high efficient, low distortion C-band Hybrid-MMIC Amplifier using linear and non-linear models of the PHEMT devices has been developed. Double stage Hybrid-MMIC amplifier fabricated with 2?3.6mm gate width PHEMT and 2?12mm gate width PHEMT exhibits a power output of 40.2 dBm at 2dB of gain compression, a linear gain of 26dB and an associated PAE of greater than 46% in the frequency range of...
Power amplifiers with high power-added efficiency appears to be one possibility to overcome the important power consumption which exists in power modules in satellites of telecommunications and satellites of observation of the earth. We have developed a straightforward technique for designing very high efficiency power amplifiers. An hybrid power amplifier was designed at X-band achieving output power...
