描述 Description

The SMP1331-085LF is a surface mountable, low capacitancesilicon PIN diode designed as a shunt connected PIN diode forhigh power, high volume switch and attenuator applications from10 MHz to beyond 6 GHz.

Maximum resistance at 100 mA is 0.5 ? and typical capacitanceat 30 V is 0.35 pF. The combination of low junction capacitance,low parasitic inductance, low thermal resistance, and nominal30 ?m I-region width, makes the SMP1331-085LF useful in largesignal switches and attenuator applications.

The device has a 2.5 W dissipation power rating, making itcapable of handling more than 50 W @ 85 °C Continuous Wave(CW) in a shunt-connected transmit/receive (T/R) switch.

Design information for high power switches may be found in theSkyworks Application Note, Design With PIN Diodes (documentnumber 200312).
