Abstract

PURPOSE:To improve the temperature characteristics of a feedback type oscillator and the aging characteristics, by distributing an input of amplifiers with a 90 degree hybrid and using the balance type amplifier synthesizing the output. CONSTITUTION:As the amplifier part of a feedback type oscillator, a balance type amplifier BA distributing and synthesizing the input and output with 90 degree hybrids H1, H2 is used. Thus, even if a parameter due to temperature change in AMP1, AMP2 is changed, the amplifier is balanced and the changing component is cancelled. Taking the characteristics of the AMPs as the same, even if the input and output impedance change, since the change is not appeared externally and the transmission phase is unchanged, the temperature and aging charcteristics can be improved.
