The SMS201 is a silicon Schottky diode in a molded
plastic DFN package. It is designed for a broadband
zero bias detector. It has a high cutoff frequency and
can be used beyond 26.5 GHz for power detection
up to 10 dBm.
• 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.
