Ka - Band Linearization
The new Ka-band communications services require highly linear, high power amplifiers (HPAs). Traveling wave tube amplifiers (TWTAs) offer the best millimeter wave HPA performance in terms of power and efficiency, but are inferior to solid state power amplifiers (SSPAs) in linearity. This paper discusses techniques for improving millimeter wave HPA linearity. The significance and methods for eva...
متن کاملKa-Bancf Mobile Expwimentsl
The National Aeronautics and Space Administration (NASA) through the Jet Propulsion Laboratory (JPL) has been involved in the development of mobile satcom technologies for more than ten years. The initial work was performed at L-band (1.5 -1.6 GHz), and included system studies and analysis, subsystem and full terminal development, and culminated in numerous field experiments and demonstrations ...
متن کاملFeasibly Reducing KAT Equations to KA Equations
Kleene algebra (KA) is the algebra of regular events. Familiar examples of Kleene algebras include regular sets, relational algebras, and trace algebras. A Kleene algebra with tests (KAT) is a Kleene algebra with an embedded Boolean subalgebra. The addition of tests allows one to encode while programs as KAT terms, thus the equational theory of KAT can express (propositional) program equivalenc...
متن کاملKA Description of Software Testing
READ ME This is Version 0.5 of the Software Testing KA Description. I have done my best to provide -within the close deadlinea preliminary document according to the specifications. However, I am heavily relying on the feedback from the first review round to improve this draft document, as I am fully aware that it still needs more work than that I could realistically put on it. Above all, some o...
متن کاملKa Band Transmit Antenna Array
Active antenna arrays working at higher frequencies result in higher packaging densities. The antenna array under consideration operates at about 30 GHz and will be installed in an aircraft. Commercially available power amplifiers at these frequencies have an efficiency of typically 20 %, which results in high amounts of dissipated heat for the required high radiated power. The dissipated power...
