Description

The SMP1345-087LF is a surface mountable PIN diode suitable for use in an RF switch or attenuator circuit. Maximum resistance at 10 mA is 2 Ω and maximum capacitance at 5 V is 0.2 pF. The combination of low capacitance, low parasitic inductance, and nominal 10 μm I-region width, makes the SMP1345-087LF useful in large signal switches and attenuator applications. The device has a 0.5 W dissipation power rating, which makes it capable of handling up to 40 W Continuous Wave (CW) and 440 W peak (1 μs pulse, 1 duty cycle) 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).
