| Abstract: | Combined with a newly developed S-band UWB solid state power amplifier, design theories and methods of UWB solid state power amplifier are introduced. Based on small-signal S parameters and I-V curve of GaAs FET, the input/output impedance matching circuits and bias circuits of GaAs FET are optimized by using microwave simulation software. The feasibility of this design is verified by making and testing the amplifier. The amplifier's performance test data are given. The amplifier can be operated at 2~4GHz frequency range. The output power is greater than 20W when the input power is 40mW, and it's gain flatness is less than 1.5dB. |
