Quad Pin Diode Pi Attenuator in SOT-25 Package

Currently Viewing:

HSMP-3866 is a wideband (300KHz to 3GHz), low insertion loss, high linearity, Quad PIN Diodes p Attenuator in a low cost, surface mount SOT-25 package. Four PIN Diodes in a single package reduces te design parasitics and improve circuit density. The four PIN Diodes dice are adjacent dice on the same wafer and therefore have very similar and matched RF performance. This improves customer's production yield at board level with better product performance and application repeatability.
