(Invited) An X-Band Class-E Power Amplifier with MEMS Output Impedance Tuner Academic Article uri icon

abstract

  • This paper presents the design, fabrication and measurements of a hybrid X-band class-E power amplifier with a MEMS output tuner that enables the power amplifier to operate at optimum efficiency and output power level despite the fabrication uncertainties/tolerances of the device and circuit. The tuner is implemented with two 2.8 : 1 analog MEMS varactors and covers an impedance range of resistance between 10 to 30 and reactance of -3 to -9 . The designed PA delivers 605 mW output power with power added efficiency of 52% at 10.5 GHz.
