Description
The SMP1321 series of plastic packaged, surface
mountable PIN diodes are designed for high volume switch
applications from 10 MHz to beyond 2 GHz. The low
capacitance of these diodes (0.25 pF) combined with its low
resistance (2.0 Ω maximum at 10 mA) make the SMP1321
series particularly suited to high isolation series connected
PIN diode switches in battery operated circuits. Available
in a selection of plastic packages and in a variety of
configurations including a low inductance (0.4 nH) SOT-23
(SMP1321-007), the small footprint SC-79 and the
miniature SC-70.
