已经设计和制造了可从11.15调到14.39GHz以及16.0调到18.74GHz的GaAsVCO(电压控制振荡器)电路。1.1mm×1.2mm芯片上包含有两个变容管、一个300μmFET以及旁路电容器、调谐电感器和隔离电阻器。叙述了宽带电路设计技术。对引起带宽不连续的变容管和电路效应进行讨论,表明用单个GaAs芯片有可能实现从11～18GHz连续调谐。
GaAsVCO (Voltage Controlled Oscillator) circuits that can be tuned from 11.15 to 14.39 GHz and 16.0 to 18.74 GHz have been designed and fabricated. The 1.1mm × 1.2mm chip contains two varactors, one 300μm FET with bypass capacitor, tuning inductor and isolation resistor. Describes the design of broadband circuit technology. A discussion of varactor and circuit effects that cause discontinuities in bandwidth shows that it is possible to tune continuously from 11 to 18 GHz with a single GaAs chip.
