Abstract
An amplifier comprising a field effect transistor, a terminating network comprising inductors connected in series separated by capacitors connected in parallel, a filter and a load, wherein the values of the capacitors and inductors are arranged to present open circuits to a predetermined number of odd harmonics of a signal frequency being amplified, and to present short circuits to a predetermined number of even harmonics of the signal frequency, wherein the normalised values of the inductors and capacitors of the terminating network are selected using the following procedure: Let gr=Cr r odd=Lr r even then g1=1, g1g2=(a); grgr+1=(b), r=2→2m−1 and g2mg2m+1=(c) where (m−1) represents the predetermined number of odd harmonics which are presented with an open circuit
