SMP1331-087LF Block Diagram Description The SMP1331-087LF is a surface mountable, low-capacitance silicon PIN diode designed as a series connected PIN diode for high-power, high-volume switch and attenuator applications from 10 MHz to beyond 6 GHz. Typical resistance at 100 mA is 0.50 Ω and maximum capacitance at 30 V is 0.35 pF. The combination of low capacitance, low parasitic inductance, and nominal 30 μm I-region width, makes the SMP1331-087LF useful in large signal switches and attenuator applications. The device has a 0.75 W dissipation power rating, which makes it capable of handling up to 45 W @ 85 °C Continuous Wave (CW) in a series-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 the SMP1331-087LF is shown in F...
