Very Low Capacitance Plastic Packaged Silicon PIN Diodes

The SMP1345 series of plastic packaged, surface mountable PIN diodes is designed for high volume Low-Noise Block (LNB), Wireless Local Area Network (WLAN), and switch applications from 10 MHz to 6 GHz. The short carrier lifetime of 100 ns (typical), combined with their thin I-region width of 10 μm (nominal) results in a group of fast speed RF switching PIN diodes.

The RF performance of the SMP1345 series is assured by virtue of their very low capacitance (0.15 pF) and low resistance (1.5 Ω at 10 mA). The SMP1345-518 has been specifically designed for WLAN 802.11 a/b/g applications. It is ideally suited for diversity switch applications.

Features

  • Very low insertion loss: 0.4 dB
  • Capacitance: 0.15 pF
  • Packages rated MSL1, 260 °C per JEDEC J-STD-020
