This antenna requires flexible, lightweight, and low loss feeders to element radiators. This module comprised of a microstrip-to-slot transition, two chips of low-noise MMIC amplifiers, and a laser diode module is fabricated on an ultrathin package with 10/spl times/30/spl times/1.5 mm3 in size and 2 g in weight to achieve an ultra-thin structure of active phased array antenna panels. To provide low noise and ultra-thin size, DCCPWs are employed in the design of input matching circuit of low-noise MMIC amplifiers. In addition, the ultra-thin structure is attributed to the design of laser diode modules using silicon V-groove technology and fiber alignment method.","PeriodicalId":176577,"journal":{"name":"International Topical Meeting on Microwave Photonics.
