The HSMP-3816 has four PIN diodes configured for PI attenuator diode applications. The four wideband , 300kHz to 4GHz, low insertion loss, high linearity, pin diodes are in a low cost, surface mount SOT-25 package. Four PIN diodes in a single package reduce parasitics and improve circuit density.
The four PIN Diode dice come from adjacent die on the same wafer and therefore have very similar and matched RF performance. This improves end-user production yield at the board level. Better product performance and application repeatability result.
