Abstract:An E-band high speed power detector MMIC using pHEMT technology has been designed, manufactured and experimentally characterized. By employing a 4-way quadrature structure for phase cancellation, the first, second and third harmonics can be suppressed and the ripple at the output is minimized. Compared to conventional topology with a low pass filter, a short response time and high speed performance of demodulation can be reached. Simulated results indicate that the detector is capable of demodulating an on-of… Show more
