| Abstract: | Abstract: A design scheme and test results of a pulse power amplifier used for high-power transmitter is presented. Cascade structure, balanced structure as well as lumped elements and micro-strip matching network is used for the design. In 2.3GHz-2.4GHz, the amplifier provides a gain of 47 ± 1.5dB, output power of 200W, and 15dB return loss. Test results show that the circuit has met the specifications. |
