Design and Implementation of an S-band Receiver for Small Satellite Based on the Manufactured Subsystems

In this work the design and implementaion of a receiver for small satellites in range of 1.9 GHz to 3.0 GHz frequency were presented. We concentrated on developing a new architecture for receiving satellites in challenging environments and integrated some of the author’s previously published designs. By using the protected mechanism for RF circuit of receiver, a mutil-stage in IF amplifier and automatic gain control in IF amplifer has been designed, this receiver has a higher gain (78 dB), a larger dynamic ranger (80 dB), a high stability and sensitivity (110 dBm) at 2.15 GHz frequency. The receiver module works well; and due to the flexible structure, easy assembly and low-cost characteristics, it can be applied for small satellites and ground stations.
