Molded Plastic DFN Package
Description
The SMS202 is a silicon Schottky diode in a molded
plastic DFN package. It is designed for a broadband
zero bias detector. It can be used up to 18 GHz and
power detection up to 10 dBm.
Features
• Small footprint, only 50 X 30 mils.
• Simplest broadband detector as no dc bias
required.
• Very low barrier height, good sensitivity,
-54 dBm typical. Also low flick noise.
• Very low parasitic package inductance and
low package capacitance.
• Cost effective choice for high volume production.
