The SMP1302-085LF is a surface mountable, low-capacitance silicon PIN diode designed by Skyworks 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 1,5 Ω and maximum capacitance at 30 V is 0,3 pF. The combination of low junction capacitance, low parasitic inductance, low thermal resistance and nominal 50 μm I-region width, makes it useful in large signal switches and attenuator applications.
The device has a 3 W dissipation power rating, making it capable of handling more than 50 W continuous wave (CW) and 500 W peak (1 μs pulse, 1% duty cycle) in a shunt-connected transmit/receive (T/R) switch.
