据《电子材料》(日)2003年第6期报道,日本松下电器产业日前开发了将压控振荡器(VCO)和锁相环(PLL)做成同一芯片的IC。5.8 GHz本振信号产生由2.9 GHz倍频电路实现,采用频率特性优越的SiGe Bi—CMOS工艺技术。 VCO/PLL单芯片IC,包含谐振部分的VCO电路都采用全封闭式小型封装形式,该芯片与MMIC芯片一起构成一个完整的车载器无线系统。 According to “Electronic Materials” (Japan) No. 6, 2003 reported that Japan’s Matsushita Electric Industrial has developed a voltage-controlled oscillator (VCO) and phase-locked loop (PLL) made the same chip IC. The 5.8 GHz local oscillator signal is generated by a 2.9 GHz frequency multiplier circuit using SiGe Bi-CMOS process technology with superior frequency characteristics. The VCO / PLL single-chip IC, the VCO circuit containing the resonating parts, are all enclosed in a small package that, together with the MMIC chip, forms a complete vehicle-mounted wireless system.
