Paper Abstract

Fiber Optic microwave links for microcellular mobile communications have gained wide spread attention in the recent years. This paper reports the analysis of a fiber optic microwave link that employs a metal semiconductor metal photodiode (MSM-PD) as an optoelectronic mixer (OEM). The OEM can considerably reduce the base station hardware in a typical microcell environment and thus economize the overall system cost. The nonlinearities inherent in the MSM-PD OEM are examined by modeling its dc responsivity as a third order polynomial function of applied bias voltage. The OEM has been analyzed in terms of its conversion loss and noise figure. The link quality has been estimated in terms of the carrier to noise ratio (CNR).
