【Abstract】 The paper describes a design method and fabrication technology of GaAs MMIC switch in airtight ceramic package. The developed GaAs MMIC SPST switch has an insertion loss of 0.3-1.4dB over DC-12GHz frequency band with a return loss of better than 11dB. An isolation increases with frequency from 19dB at DC to 27dB at 12GHz. The SPST switch demonstrates a switching time less than 1ns and a power-handling capability of batter than 25dBm at 8GHz.更多还原
