    摘要： A surface-mountable mm-wave signal source is provided. The surface-mountable mm-wave signal source comprises: a conductive metal base; a mm-wave signal source disposed over an upper portion of the metal base; a first radio frequency transmission line carrying a quasi-TEM signal from the mm-wave signal source, which is disposed over an upper portion of the metal base and proximate the signal source; a first mode transformer at least partially integrated into the upper portion of the metal base to convert the quasi-TEM signal carried by the planar transmission line into a rectangular waveguide mode signal; a waveguide well having upper and lower ends disposed within the base for carrying the rectangular waveguide mode signal from an upper portion of the base to a lower portion of the base; and a second mode transformer at least partially integrated into the lower portion of the base to convert the rectangular waveguide mode signal to a quasi-TEM signal within a second radio frequency transmission line. The mm-wave signal source preferably operates in a frequency range of from 35 to 94 GHz, more preferably a frequency range of 70 to 80 GHz.

    摘要： Disclosed is a hard disk drive carrier adapted to be housed in a disk drive chassis comprising a drive bay for receiving and holding a hard disk drive; an integrated locking mechanism including a handle for carrying the disk drive carrier and for providing a one-handed locking mechanism for locking and unlocking the disk drive carrier in the disk drive chassis; and an EMI shield fixedly coupled to the drive bay for providing a barrier to electromagnetic interference, the EMI shield covering a portion of the hard disk drive. Also disclosed is a hard disk drive bay including opposing sidewalls for securing a hard disk drive into a chassis comprising a primary locking mechanism, the primary locking mechanism comprising first and second swing arms each pivotally coupled to said drive bay at a first pivot point and pivotally coupled to a handle at a second pivot point; and a secondary locking mechanism disposed on one or both of said opposing sidewalls, the secondary locking mechanism adapted to interface with corresponding locking elements disposed on the hard drive chassis.
