Skyworks Intros 0402 PIN Diode for Transmit/Receive Switching Applications
May 31, 2013
Skyworks Solutions, Inc. has introduced a miniature 0402 PIN diode for
attenuator and transmit/receive switching applications. The
is a small form factor, low profile, discrete surface mount technology packaged solution that
is ideal for the handset, WLAN, CATV/Satcom, land mobile radio and infrastructure markets.
This diode offers very low insertion loss, good isolation, low inductance and fast switching
in a very small package.
The SMP1302 series of plastic packaged, surface mountable,
low capacitance (0.3 pF) silicon PIN diodes is designed for high volume switch and attenuator
applications from 10 MHz to beyond 2 GHz.
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, makes these diodes useful in large signal switch applications.
The SMP1302 series
provides single and dual diodes in a selection of plastic packages including SOT-23, SOD-323,
small footprint SC-79, an ultralow inductance (0.2 nH) SOT-143 (SMP1302-017), and miniature
A four-diode array is available in an SOT-5 package (SMP1302- 027) designed for
insertion in the commonly used four-diode PI attenuator circuits.
