RESONANT FREQUENCY-TEMPERATURE CHARACTERISTICS COMPENSABLE HIGH FREQUENCY CIRCUIT ELEMENTAL DEVICE

摘要

High frequency circuit elemental device A high frequency circuit elemental device comprising a casing and a dielectric ceramic mounted in said casing, such as oscillators, said dielectric ceramic being capable of under going order-disorder structural transformation, whereby the temperature coefficient of the resonant frequency of said elemental device can be compensated by heat-treatment of the dielectric ceramic.
