Switch and Attenuator
Plastic Packaged PIN Diodes
SMP1302 Series
Features
■Low Distor tion Design
■Frequency Range from HF to > 2 GHz
■Designed for Base Station and Handset
Applications
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 bey ond 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 Ωat 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.A v ailable in a SO T-5 (SMP1302-027) package as
a f our diode arra y designed for insertion in the commonly
used 4 diode PI attenuator circuit.
