ABSTRACT:
A method and apparatus are provided for implementing direct attenuation loss measurement in an electronic package. A sinusoidal voltage source signal of a selected frequency is coupled to an embedded transmission line test structure in the electronic package. Receive circuitry is coupled to the transmission line test structure for detecting amplitude of a received sinusoidal voltage source signal to identify attenuation loss through the transmission line test structure. An identified attenuation loss of the transmission line test structure is compared with a threshold value for verifying acceptable attenuation of the electronic package transmission line test structure.
