Broadband high frequency low noise amplifiers for connected phased array feeds

A low noise amplifier (LNA) with 30 K noise temperature over a wide frequency range from 0.9 to 3.5 GHz is presented. The LNA to be described is suitable for high frequency connected arrays such as Phased Array Feeds (PAFs) operating in the 0.5 to 4 GHz frequency range. The LNA is implemented with unpackaged transistors. It combines single ended… CONTINUE READING
