Description
The SMP1322 series of plastic packaged, surface
mountable PIN diodes are designed for high volume switch
applications from 10 MHz to beyond 2 GHz. The ultra low
resistance of these diodes (1.5
Ω
maximum at 1 mA and
0.5
Ω
typical at 10 mA) make the SMP1322 series
particularly suited to low loss PIN diode switches in battery
operated circuits. Available in a selection of plastic
packages and in a variety of configurations including an
ultra low inductance (0.2 nH) SOT-143 (SMP1322-017),
the small footprint SC-79 and the miniature SC-70. In
addition, the SMP1322-016 consists of 2 diodes in a
SOT-143 package configured to enable insertion in a
quarter-wave T/R switch with no crossover connections.
