S-band receiver front-end design for portable satellite ground terminal

This paper describes the low noise and high gain front-end S-band receiver for the portable satellite ground terminal for the voice, video and data communication mainly at the time of disaster like earthquake and tsunami or at the remote area where land based networks are not present. This design is having very low noise figure, high gain and low spurious levels. Channel is selected at the RF frequency with the use of synthesizer. Low Noise, compact size, low power consumption, and low cost are the satisfaction for developed unit.
