Abstract :
Voltage sensitivities of planar doped barrier (PDB) detector diodes as high as 17.4 mV/μW at 10 GHz and 28.6 mV/μW at 35 GHz have been achieved. In comparison with that of existing devices, these values are three to ten times higher, implying the diodes can detect much lower power hence widening the dynamic range of microwave/millimeter-wave detectors.
