DATA SHEET SMS7630-061: Surface Mount, 0201 Zero Bias Silicon Schottky Detector Diode Applications Sensitive RF and microwave detector circuits Sampling and mixer circuits High volume wireless systems WiFi and mobile devices Low-noise receivers for high sensitivity ID tags Radio designs Description Features 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. Extremely low barrier height Suitable for use above 26 GHz Low parasitic impedance: CP < 0.05 pF, LS < 0.2 nH 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. Low profile, ultra-miniature 0201 SMT package (MSL1, 260 C per JEDEC J-STD-020) A pinout diagram for the SMS7630-061 is shown in Figure 1. Skyworks GreenTM products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Definition of GreenTM, document number SQ04–0074.

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). A rat-race mixer that uses two SMS7630-061 Schottky diodes is shown in Figure 4. The LO signal (24 GHz) is fed from the right side and reaches a rat-race ring. The diodes are positioned 90 degrees apart from the LO input and are terminated in a stub. 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 pF capacitor. The output voltage is fed to a 2-pin, 2.54 mm header. Both diodes are connected (using a 1206 resistor) and are loaded by a 470 Ω resistor and a 10 pF capacitor. This forms the IF output (10 MHz). The RF input (24.010 GHz) is directly connected to the rat-race ring. A layout design is illustrated in Figure 5. 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. Input power versus detected voltage for this detector is shown in Figure 8. The mixer has been tested with the following conditions: LO frequency: LO power: RF frequency: RF power: 24 GHz –4 to +6 dBm 24.010 GHz –30 dBm Typical conversion loss data for this mixer is shown in Figure 9. λ/4 RF Input SMS7630-061 Detected Voltage RF Input λ/4 SMS7630-061 λ/4 λ/4 3λ/4 LO Input λ/4 100 pF SMS7630-061 λ/4 λ/4 100 kΩ IF Out λ/4 100 kΩ 100 pF Figure 2.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
