Abstract :
A review of the radar duplexer and receiver, as developed during the war, is presented. Attention is devoted to the principles of operation and typical circuit arrangements employed in the duplexer, the crystal converter, the local-oscillator injection circuits, the intermediate-frequency amplifier, and the automatic-tuning unit. Emphasis is placed on methods found advantageous in the 1-centimeter and 3-centimeter wavelength regions. The interrelation between the various receiver components in determining the over-all receiver noise figure is shown analytically, and typical performance numbers are given.
