This volume describes the design of various microwave circuits the have been used as mixers in the microwave region an the Radiation Laboratory. The mixers convert the microwave signal into a signal at a lower frequency, where conventional lumped-constant circuits and multiple-element vacuum tubes are used. For information concerning the design of a complete microwave superheterodyne receiver, of which the mixer is a part, Vol. 23 of this series is recommended. Low frequency amplifiers of many types, for use following the mixer, are described in Vol. 18. A complete treatment of clystal rectifiers, which are the hearts of the mixers described in the present volume, is given in Vol. 15, Duplexing circuits often required in pulse radar, and the tubes used in them are described in Vol. 14. Low-level oscillators, which are used as local oscillators for the mixers, are trested in Vols. 7 and 11.
