<title>Millimeter wave monolithic components for sensor applications</title>

Abstract

ABSTRACT State-of-the-art millimeter-wave monolithic power components have been developed for Ka- andW-band sensor system applications. This paper presents the development and perfonnance of Ka- and W-band power MIMIC components. At W-band. the integrated power module using U-band MIvITC poweramplifiers in conjuction with W-band MIMiC doubler shows the highest reported 1o\ver (95 mW) and gain at 94 GHz. At Ka-band. a four-stage power amplifier exhibited 14.6 dB of linear gain and 300 mWsaturated 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. 1. INTRODUCTION The next generation millimeter-wave systems such as collision avoidance and mm-wave seekersystenis require the insertion of IVIIMIC components to make them affordable. Monolithic millimeter-wave integrated circuits (MMICs) offer the best potential for cost reduction. perfonuance enhancement. andreliability improvenient for such systems. Considerable effort is therefore being directed toward thedevelopment and low cost production of monolithic millimeter-wave integrated circuit components formissile seeker, auto collision avoidance sensors and PCN system applications. 94 GHz and 35 GHzmonolithic power transmitters are critical for such applications at W- and Ka-band. However. no such
