An Improved Active Mixer Architecture for Millimeter Wave Applications

International Journal of Information and Communication Technology Research, 2011
Modified active mixer architecture is presented in this paper which improves the gain and noise figure of the mixer considerably. The architecture of the mixer allows wide band operation from very low frequencies up to millimeter - wave regime.

Noise and noise figure in microwave receivers

, 1949
The investigation of noise and noise figure in microwave receivers was commenced in the fall of 1948 at the U. S. Naval Postgraduate School and was continued through the winter in the electronics laboratory of the Glenn L. Martin Company at Middle River, Maryland. This field work was done to give the writer experience in the measurement of noise figure
