SMP1321-075 Product details
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. The SMP1321-508 has been specifically designed for WLAN 802.11 a, b, and g applications.
