Description
The SMP1302-085LF 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 1.5 Ω and maximum
capacitance at 30 V is 0.35 pF. The combination of low junction
capacitance, low parasitic inductance, low thermal resistance,
and nominal 50 μm I-region width, makes the SMP1302-085LF
useful in large signal switches and attenuator applications.
The device has a 2.8 W dissipation power rating, making it
capable of handling more than 140 W Continuous Wave (CW) and
500 W peak (1 μs pulse, 1 percent duty cycle) 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 the SMP1302-085LF is shown in Figure 1.
