UM9701

WWW.Microsemi .COM UM9701 Low Resistance, Low Distortion, RF Switching PIN Diode DESCRIPTION The UM9701 PIN diode was designed for low resistance at low forward bias current and low reverse bias capacitance. This unique Microsemi design results in both forward and reverse bias. These PIN diodes are characterized for low current drain RF and microwave switch applications particularly for digital filter switch designs. The construction and geometry of these devices provide good voltage and power handling capability. These devices are constructed using a metallurgical full face bond to both surfaces of the silicon chip. A glass enclosure houses this bond in a reliable and hermetic package. The axial leads are attached to refractory pins and do not touch the glass enclosure. Environmentally these, and all Microsemi PIN diodes, can withstand thermal cycling from -195 °C to + 300 °C and exceed all military environmental specifications for shock, vibration, acceleration, and moisture resistance.
