Description The SMS7630-061 is a silicon, zero bias Schottky detector diode with an ultra-miniature 0201 footprint and very low barrier height. This P-type diode can be used for sensitive video detector circuits and sampling circuits. The low barrier height results in good detector sensitivity without the need for external bias current. The low junction capacitance of this diode makes it an excellent detector at frequencies up to 26 GHz and higher. A pinout diagram for the SMS7630-061 is shown in Figure 1.

The RF arrives on a 50 Ω microstrip line from the left and is shorted to GND by a 90 degree line with a stud (GND arrives by a via). The cathode of the diode is directly connected to a 24 GHz stub. This output is loaded by a 100 kΩ resistor and a 100 p F capacitor. The output voltage is fed to a 2-pin, 2.54 mm header. The circuit was built on a 0.254 mm Rogers RO-4350B substrate and measured with a power-variable 24 GHz source. A layout design is illustrated in Figure 3.
