Abstract :
The paper reports on the design features and development of a thermostable stripline lumped element circulator operating in the above resonance mode. Improvements in insertion loss and temperature stability were achieved by virtue of a new integral topology for the conductors´ crossover and a novel arrangement of the DC magnetic circuit. Circulator prototypes demonstrated excellent performance in the frequency range 70-400 MHz.
