Silicon Schottky P-Type Diodes Zero Bias

MACOM’s diodes are fabricated on P-Type substrates for low 1/f noise and are optimized for zero-bias operation. Zero-biased devices are processed to yield two distinct video impedance classes, one 1,500 Ohms typical and the other 4,000 Ohms typical. Applications requiring maximum stability and sensitivity will favor the higher video impedance. Biased detector operation offers the designer improved temperature stability and video impedance flexibility via bias current selection.
