    • The invention provides a method and apparatus for packaging high frequency electrical and/or electro-optical components. The package (140) may be surface mounted on a board with other electrical components. The shielding provided by the package minimizes electromagnetic interference with other electrical components on the board. The package includes a controlled impedance I/O interface for coupling with the electrical or electro-optical components in the package. The interface may also include a differential I/O capability to further control electromagnetic fields generated at the interface. Additionally, the package may include an optical link provided by one or more optical fibers (150) extending from the package. These features allow the package to be used for a variety of high frequency components including optical transmitters (254) and optical receivers. A method for fabricating the package is also disclosed. The package may be fabricated with relatively low cost and a reduced form factor as compared with prior art packages.
    • 本发明提供了一种用于封装高频电和/或电光部件的方法和装置。 封装(140)可以表面安装在具有其它电气部件的板上。 封装提供的屏蔽最大程度地减少电路板上其他电气元件的电磁干扰。 该封装包括用于与封装中的电气或电光部件耦合的受控阻抗I / O接口。 接口还可以包括差分I / O能力,以进一步控制在接口处产生的电磁场。 另外,封装可以包括由从封装延伸的一个或多个光纤(150)提供的光学链路。 这些特征允许封装用于各种高频部件,包括光发射器(254)和光接收器。 还公开了一种制造封装的方法。 与现有技术的封装相比,封装可以以相对较低的成本和减小的外形尺寸来制造。

    • A ceramic microelectronic package (200) suitable for housing high-frequency electronic devices, and a process for making such a package, are disclosed herein. The package includes a base (102), a ceramic circuit substrate (106) attached to a top surface of the base and having a first cavity for receiving a high-frequency electronic device (116), and conductive patterns (202) deposited on a surface of the circuit substrate. The patterns (204) include signal patterns and flanking ground patterns forming at least a portion of co-planar waveguide (CPW) transmission lines. Each signal pattern is preferably a signal trace, and each ground pattern may be a ground trace or plane. The ground patterns may each have a portion exposed outside the package for external connection to electrical ground. Alternately, the ground patterns may be internally connected to a ground plane formed by the base, when the base is at least partially conductive, by conductive via openings or bonding wires passing through ears cut into a perimeter of the circuit substrate. The base may also be non-conductive such that the transmission line is a suspended CPW transmission line. The package may include a ceramic seal ring (110) substrate attached to the circuit substrate and having a second cavity larger than the first cavity, and a ceramic lid (114) attached thereto such that the transmission line forms a CPW, embedded CPW, and CPW transmission line. Alternatively, the package may include a dielectric sealing cap attached to the circuit substrate and having a chamber larger than the first cavity such that the line again forms a CPW, embedded CPW, and CPW transmission line.
    • 本文公开了一种适用于容纳高频电子器件的陶瓷微电子封装(200)及其制造方法。 所述封装包括基座(102),陶瓷电路基板(106),所述陶瓷电路基板(106)附接到所述基座的顶表面并具有用于接收高频电子器件(116)的第一腔,以及沉积在所述基座 电路基板的表面。 图案(204)包括形成共面波导(CPW)传输线的至少一部分的信号图案和侧面接地图案。 每个信号图案优选地是信号迹线,并且每个接地图案可以是接地迹线或平面。 接地图可以各自具有暴露在封装外部的部分,用于外部连接到电气接地。 或者,当基底至少部分导电时,接地图案可以内部连接到由基底形成的接地平面,通过导电通孔开口或穿过切入电路基板的周边的耳朵的接合线。 基座也可以是非导通的,使得传输线是悬挂的CPW传输线。 封装可以包括附接到电路基板并且具有大于第一空腔的第二空腔的陶瓷密封环(110)和附接到其上的陶瓷盖(114),使得传输线形成CPW,嵌入式CPW,以及 CPW传输线。 替代地,封装可以包括附接到电路基板并具有大于第一空腔的室的电介质密封盖,使得线再次形成CPW,嵌入式CPW和CPW传输线。
