Title:
温度依存性の少ないバラクタ機器
Document Type and Number:
Japanese Patent JP2008516444
Kind Code:
A
Abstract:
The invention discloses a varactor device (100) for improved temperature stability, comprising a first varactor (160) connected to a decoupling network (150). The device further comprises a voltage stabilizer (110), said stabilizer comprising a capacitor (140) and a temperature dependent capacitor (130), and in that the stabilizer comprises means for connection to a DC-feed (120). Suitably, the decoupling network (150) is connected in parallel to the first varactor (160), and the capacitor (140) of the voltage stabilizer (110) is connected in parallel to the decoupling network (150), the temperature dependent capacitor (130) of the voltage stabilizer (110) being connected in series to the diode of the voltage stabilizer (110).
