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 Figure 1.
