Features
Description
 AEC-Q101 qualified
The SMSA7630-061 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.
 ISO/TS16949 certified facility
 Excellent sensitivity
 Suitable for use up to 77 GHz
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
77 GHz and higher.
 Low parasitic impedance: CP < 0.05 pF, LS < 0.2 nH
 Low profile, ultra-miniature 0201 SMT package
(MSL1, 260 C per JEDEC J-STD-020)
A pinout diagram for the SMSA7630-061 is shown in Figure 1.
Skyworks GreenTM products are compliant with
all applicable legislation and are halogen-free.

Mixer and Detector Applications
24 GHz Detector Design
24 GHz Rat-Race Mixer
A detector circuit that incorporates an SMSA7630-061 Schottky
diode and covers the 24 GHz band is shown in Figure 2. 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 SMSA7630-061 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:

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.
