The SMP1321 series of plastic packaged, surface mountable PIN diodes is designed for use in high volume switch applications from 10 MHz to more than 2 GHz. The low capacitance of these diodes (0.25 pF), combined with a low resistance (2.0 Ω maximum at 10 mA), makes the SMP1321 series particularly suited to high isolation, series-connected PIN diode switches in battery operated circuits.?
The SMP1321 series is available in a selection of plastic packages and a variety of configurations that include a low inductance SOT-23 (0.4 nH), a small footprint SC-79, and a miniature SC-70. The SMP1321-508 has been specifically designed for WLAN 802.11 a/b/g applications.
Capacitance: 0.25 pF
