Description
The SMP1302 series of plastic packaged, surface
mountable, low capacitance (0.3 pF) silicon PIN diodes
are designed for high volume switch and attenuator
applications from 10 MHz to beyond 2 GHz. These diodes
are designed for use in low distortion PI and TEE
attenuators with low drive current (maximum resistance
at 1 mA is 10
Ω)
commonly used in TV distribution and
cellular base station applications. The nominal 50
µm
I region width combined with a maximum resistance of
3
Ω
at 10 mA, make these diodes useful in large signal
switch applications. Available as single and dual diodes
in a selection of plastic packages including SOT-23,
SOD-323, small footprint SC-79 and miniature
SC-70. Available in a SOT-5 (SMP1302-027) package as
a four diode array designed for insertion in the commonly
used 4 diode PI attenuator circuit.
