  • On-chip integrated mixer with balun circuit and method of making the same
    Patent number: 6653885
    Abstract: A radio frequency (RF) mixing device wherein RF core circuit elements requiring signal splitting are provided with one or more signal splitting element(s) (“balun(s)”) integrated on-chip with the core RF circuit elements. The RF mixing device comprises one or more RF circuit element(s) integrated on a common substrate with one or more balun(s), wherein the common substrate is an insulating substrate further provided with associated silicon-based CMOS circuitry formed in a thin, highly crystalline silicon layer formed on the insulating substrate. The insulating substrate is selected from transparent crystalline materials such as sapphire, spinel, etc. The common substrate is preferably ultrathin silicon-on-sapphire.
    Type: Grant

  • Control arm for use in a vehicle wheel suspension system
    Patent number: 5556119
    Abstract: A control arm (30) comprises a first member (32) with a first portion (42) connectable to a vehicle frame (38). A second portion (56) of the first member (32) is connectable to a steering knuckle (14). A connecting portion (64) interconnects the first and second portions (42, 56) of the first member (32). A second member (34) includes a third portion (68) connectable to the vehicle frame (38) and a rod portion (84) extending from the third portion (68). The rod portion (84) includes a terminal end (86) rigidly connected to the connecting portion (64) of the first member (32) to prevent relative movement between said first and second members.
