Abstract
State-of-the-art millimeter-wave monolithic power components have been developed for Ka- and W-band sensor system applications. This paper presents the development and performance of Ka- and W-band power MMIC components. At W-band, the integrated power module using U-band MMIC power amplifiers in conjuction with W-band MMIC doubler shows the highest reported power (95 mW) and gain at 94 GHz. At Ka-band, a four-stage power amplifier exhibited 14.6 dB of linear gain and 300 mW saturated output power at 35 GHz. These power modules are highly stable and suitable for the future millimeter-wave sensor system applications, such as PCN and collision avoidance sensors.
