Communication satellite power amplifiers: current and future SSPA and TWTA technologies
(Wiley, 2016-04)
This study captures the state of current satellite transponder technology, specifically, solid-state power amplifiers (SSPAs) and traveling wave tube amplifiers (TWTAs), and describes expected future advances, including ...
Mars atmospheric CO2 condensation above the north and south poles as revealed by radio occultation, climate sounder, and laser ranging observations
(Journal Of Geophysical Research-Planets, 2012-07-10)
We study the condensation of CO2 in Mars' atmosphere using temperature profiles retrieved from radio occultation measurements from Mars Global Surveyor (MGS) as well as the climate sounding instrument onboard the Mars ...
Response of geostationary communications satellite solid-state power amplifiers to high-energy electron fluence
(AGU Space Weather, 2015-05-25)
The key components in communications satellite payloads are the high-power amplifiers that amplify the received signal so that it can be accurately transmitted to the intended end user. In this study, we examine 26 amplifier ...
