Description
Low profile, ultra-miniature 0201 SMT package
(MSL1, 260 C per JEDEC J-STD-020)
The SMS7621-060 is a silicon, low-barrier N-type Schottky diode
with an ultra-miniature 0201 footprint. This diode can be used in
detector circuits, sampling circuits, and mixer circuits.
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 low series resistance of this low-barrier diode enables good
performance as a low-level mixer at frequencies up to 26 GHz
and higher.
A pinout diagram for the SMS7621-060 is shown in Figure 1.

Mixer and Detector Applications
24 GHz Detector Design
24 GHz Rat-Race Mixer
A detector circuit that incorporates an SMS7621-060 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 stub (GND arrives by a via).
A rat-race mixer that uses two SMS7621-060 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.
The mixer has been tested with the following conditions:
LO frequency: 24 GHz
Input power versus detected voltage for this detector is shown in
Figure 8.
LO power:
RF frequency: 24.010 GHz
RF power: –30 dBm
0 to +5 dBm
The IF output was loaded with 50 Ω. Measured conversion loss
data for this mixer is shown in Figure 9.

The absolute maximum ratings of the SMS7621-060 are provided
in Table 1. Electrical specifications are provided in Table 2. The
associated SPICE model parameters are provided in Table 3.
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
Typical performance characteristics are shown in Figures 6
through 9.
The SMS7621-060 is rated to Moisture Sensitivity Level 1 (MSL1)
at 260 C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.

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.
