Description
The SMP1340 series of plastic packaged, surface
mountable PIN diodes are designed for high volume switch
applications from 10 MHz to beyond 2 GHz. The short
carrier lifetime of typically 100 nS, combined with its thin
I region width of nominally 8
m, results in a fast speed
RF switching PIN diode. The RF performance of the
SMP1340 series is assured by virtue of its low
capacitance (0.3 pF) and low resistance (1.0
at 10 mA).
