Abstract :
We describe analysis and design of two low-noise amplifiers (LNAs) suitable for connected array Phased Array Feeds (PAFs) operating in the 0.4 to 2 GHz frequency range. The LNAs combine single ended configurations to form balanced amplifiers with differential signal- and noise-match impedances in the order of 300Ω. Simulation results show noise temperatures of 20 K to 30 K for the 0.45 to 0.9 GHz band and 30 K to 45 K for the 0.9 to 2.0 GHz band.
