Patent number: 8472884Abstract: Microelectronics have now developed to the point where radiation within the terahertz frequency range can be generated and used. Here, an integrated circuit or IC is provided that includes a phased array radar system, which uses terahertz radiation. In order to accomplish this, several features are employed; namely, a lower frequency signal is propagated to transceivers, which multiplies the frequency up to the desired frequency range. To overcome the losses from the multiplication, an injection locked voltage controlled oscillator (ILVCO) is used, and a high frequency power amplifier (PA) can then be used to amplify the signal for transmission.Type: GrantFiled: September 9, 2010Date of Patent: June 25, 2013Assignee: Texas Instruments IncorporatedInventors: Brian P.
