A Ka-Band Compact Integrated Transmitter for VSAT Satellite Communication Ground Terminal

This paper describes the design and performance of a new compact and low cost Transmitter for Ka band VSAT satellite communication ground terminal. The main features of the transmitter are: 32.5dBm minimum output power for -16 dBm input power over the frequency range of 27.5-31GHz. The Transmitter consists of low power MMIC amplifier, band pass filter, a medium power MMIC amplifier, a four way microstrip power divider, a high power module with four MMIC power amplifiers, a four way waveguide power combiner and DC supply unit. The Transmitter size is 15.5×11×2.5 cm and weighs less than 0.6 Kg.
