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 7
µm,
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
Ω
at 10 mA).
The SMP1340-508 has been specifically designed for
WLAN 802.11 a, b, and g applications.
NEW
Lead (Pb)-Free “environmentally friendly”
packaging available: Skyworks offers the
SMP1340-079LF and SMP1340-508 Lead
(Pb)-Free package as a green alternative.
