    • A package to encapsulate an optical component includes a RF interface to receive high frequency signals from an external source. The RF interface pins that can be configured as one or more single-ended transmission lines or as one or more differential transmission lines. For example, the RF interface includes four pins that can be coupled in one of two configurations to provide a single-ended transmission line and in a third configuration to provide a differential transmission line. In one embodiment, the first, second, and fourth pins are coupled to ground while the second pin is coupled to receive a RF signal. Alternatively, the first, second and fourth pins are coupled to ground and the third pin is coupled to receive a RF signal. For a differential transmission line, the first and fourth pins are coupled to ground while the second and third pins are coupled to receive a differential RF signal.
    • 用于封装光学部件的封装包括用于从外部源接收高频信号的RF接口。 可将RF接口引脚配置为一个或多个单端传输线或一个或多个差分传输线。 例如,RF接口包括可以以两种配置之一耦合以提供单端传输线的四个引脚,并且在第三配置中提供差分传输线。 在一个实施例中,第一,第二和第四引脚耦合到地,而第二引脚被耦合以接收RF信号。 或者,第一,第二和第四引脚耦合到地,并且第三引脚被耦合以接收RF信号。 对于差分传输线,第一和第四引脚耦合到地,而第二和第三引脚被耦合以接收差分RF信号。
