Abstract
Future generations of space-based communications and surveillance platforms will be based on large-aperture phased array antennas composed of numerous active MMIC-based transmit/receive (T/R) modules. T/R modules are to be linked to the central processing unit through high-speed fiber-optic networks. These fiber networks have many advantages over traditional coaxial and waveguide signal feeds, the primary advantages being a substantial weight reduction and simplification of signal routing. Systems with higher carrier frequencies that operate up to Ka-band are also of interest. In this presentation, performance of an optimized 18.5–19.O-GHz fiber-optic link is demonstrated. The motivation is the desire to reduce high insertion losses through reactive matching and on-fiber lensing techniques.
