SMP1331-085LF Block Diagram Description The SMP1331-085LF is a surface mountable, low capacitance silicon PIN diode designed as a shunt connected PIN diode for high power, high volume switch and attenuator applications from 10 MHz to beyond 6 GHz. Maximum resistance at 100 mA is 0.5  and typical capacitance at 30 V is 0.35 pF. The combination of low junction capacitance, low parasitic inductance, low thermal resistance, and nominal 30 m I-region width, makes the SMP1331-085LF useful in large signal switches and attenuator applications. The device has a 2.5 W dissipation power rating, making it capable 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 the Skyworks Application Note, Design With PIN Diodes (document number 200312). A block diagram of t...
