Abstract
The purpose of this paper is to introduce a new type of circuit for matched amplification using negative resistance devices. This circuit consists of a quarter-wave transmission line section whose input and output are paralleled by negative conductances. The characteristics of such an amplifier are discussed, and an expression for its noise figure is derived. The development of a 30-Mc amplifier using two Esaki diodes is described. Experimental results are presented, including curves of the characteristics as a function of frequency. A gain of 8.9 db was measured with a noise figure of 4.3 db.
