Description
The SMP1331-085LF 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 0.5  and typical capacitance
at 30 V is 0.35 pF. The combination of low junction capacitance,
low parasitic inductance, low thermal resistance, and nominal
30 m I-region width, makes the SMP1331-085LF useful in large
signal switches and attenuator applications.
The device has a 2.5 W dissipation power rating, making it
capable of handling more than 50 W @ 85 °C Continuous Wave
(CW) 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 SMP1331-085LF is shown in Figure 1.
