Six (06) Watt Solid State Power Amplifier (SSPA) has been designed and developed with over all gain of 60 dB and gain flatness of ±0.7 dB at standard C-band (3.7 to 4.2GHz). Radial stubs have been inserted in Short Circuited Shunt Stub (SCSS) to solve problem of impedance pulling faced in using Internally Matched Transistors (IMTs). P1dB Compression Point, Gain Flatness over entire bandwidth and Intermodulation Products (IMs) of the SSPA have been tested and measured. Test results and the integration of the indigenously designed and developed SSPA are presented in this paper. |
