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 g hz. typical resistance at 100 ma is 0.50 and maximum capacitance at 30 v is 0.35 pf. the combination of low capacitance, low parasitic inductance, and nominal 30 m 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 figure 1.
