Title:
自動安定化ヒータ制御発振トランジスタ
Document Type and Number:
Japanese Patent JP3917177
Kind Code:
B2
Abstract:
A frequency stable oscillating device includes an oscillating transistor. A heating element is disposed in close proximity to the oscillating transistor. A temperature sensor is mounted in close proximity to the oscillating transistor. A temperature control device supplies a variable signal which is dependant upon a local temperature of the oscillating transistor, wherein the variable signal controls the operation of the heating element. The heating element may alternately consist of one or more resistive patches, or one or more heating transistors which are biased to provide sufficient heating. The oscillating device may be formed from either IC or MMIC technologies, and may be formed from either silicon or GaAs.
