| Very Low Capacitance Plastic Packaged PIN Diodes SMP1345 Series Features Designed for High Isolation LNB, WLAN and Wireless Switch Applications 0.15 pF Capacitance Available Lead (Pb)-Free MSL-1 @ 250C per JEDEC J-STD-020 Available in Tape and Reel Packaging Description The SMP1345 series of plastic packaged, surface mountable PIN diodes are designed for high volume LNB, WLAN and switch applications from 10 MHz to beyond 2 GHz. The short carrier lifetime of typically 100 nS, combined with its thin I region width of nominally, 10 m, results in a fast speed RF switching PIN diode. The RF performance of the SMP1345 series is assured by virtue of its very low capacitance (0.15 pF) and low resistance (1.5 at 10 mA). The SMP1345-518 has been specifically designed for WLAN 802.11 a, b, and g applications.
