Design and manufacture power pre-amplifier module for transmitter of ground station at S-band

Abstract

Small satellite become the trend in the future because mass, size, capabilities, cost and their combination. Compared with traditional satellite, small satellite have shorter development cycles, need smaller development team, lower launch costs, lower production costs. Small satellite include Nanosatellite. This paper targeted at design, fabrication of the power pre-amplifier module for the transmitter of Nanosatellite and its ground station operate in the frequency range 2.1 – 2.3 GHz. This power pre-amplifier to provide high output power and impedance matching with the fore-and-aft circuit of this module. By using SHF-0589 device combined with BLM7G1822S in module, its power output obtained around 23.5 dBm. With this result, it will assist the main power amplifier to achieve a highest power output.
