Description
The SMP1345 series of plastic packaged, surface mountable PIN
diodes is designed for high volume LNB, WLAN and switch applica-
tions from 10 MHz to 6 GHz. The short carrier lifetime of typically
100 ns, combined with its thin I region width of nominally, 10
µm,
results in a fast speed RF switching PIN diode. The RF performance
of the SMP1345 series is assured by virtue of its very low capaci-
tance (0.15 pF) and low resistance (1.5
Ω
at 10 mA).
The SMP1345-518 has been specifically designed for WLAN
802.11 a, b, and g applications. It is ideally used for diversity
switch applications.

Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
NEW
Skyworks offers lead (Pb)-free “environmentally
friendly” packaging that is RoHS compliant
(European Parliament for the Restriction of
Hazardous Substances).
CAUTION:
Although this device is designed to be as robust as
possible, Electrostatic Discharge (ESD) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
