<title>Development and antenna-range demonstration of an 8-element optically powered directly modulated receive fiber optic manifold</title>

Abstract

We describe the development and antenna range demonstration of a UHF 8element optically-powered directly-modulated fiberoptic manifold. Active laser diode drive circuits are used to increase the laser diode sensitivity and reduce the link noise figure. The manifold operates over the 340-400 MHz band, it consumes low power (55 mA @ 4 V per channel), has a two-tone dynamic range of 69 dB/MHz and a noise figure of 2.4 dB.
