Design of GaAs MMIC tuned front-end optical receivers for use in lightwave subcarrier multiplex systems

Much interest is currently being shown in the design of very low noise tuned front-end optical receivers for use in lightwave subcarrier multiplex (SCM) systems. This paper is concerned with the design and realization of such receivers using GaAs MMIC technology. The use of such technology, while desirable as it enables close control to be exercised over tuning element values, does complicate the design process, as well as imposing certain constraints upon noise performance of the amplifier. It is these areas that this paper addresses. Here a generalized design approach is presented which is then applied to the design and analysis of a 6 GHz parallel tuned front-end receiver to be realized using the GEC/Marconi F20 foundry process.
