A monolithic microwave integrated circuit (MMIC) switch chip is developed using the InGaAs/GaAs p-HEMT process for the switch matrix of a satellite communication system. An absorptive MMIC switch is designed for good reflection-coefficient performances of the input and output ports at both on-and of

β¦ Synopsis
In this paper the development of a channel model for wireless indoor communication, specifically with regard to indoor retransmission of satellite signals and reception by fixed and portable receivers in the L band, is described. The study is confined to the channel model, though it does not include the assessment of particular transmission forms. The theories and approaches used in the model are mainly derived from the field of mobile communication. They are combined to a straightforward chain from large-to small-scale variations yielding information about the several stages of fading. One of the features is the evaluation of the complex field distribution across a local area that can be transformed into a time-varying fading when assuming a moving receiver or a non-stationary environment.

This paper is concerned with channel modelling for satellite personal communications and with the associated problem of performance evaluation. Channel characteristics for personal communications tend to differ from those traditionally accepted for vehicular communications. In this paper we report o
## Abstract This paper presents a 60 GHz radio over fiber communication system for highβdataβrate ATM indoor transmission. The radio interface is fully MMIC integrated (OMMIC ED 0.2 AH foundry). The system has been successfully tested in an indoor environment for a data rate up to 100 Mbits/s.βΒ© 20
