SFQ-75379312-1212SF-N1

Rev 1.1

Description:
Model SFQ-75379312-1212SF-N1 is an E Bandquadrature mixer that covers the frequency range of
75 to 79 GHz. The typical conversion loss of thequadrature mixer is 12 dB with an LO driving powerof +16 dBm. The typical LO to RF port isolation is 30
dB. Since the IF port of the quadrature mixer is DC
coupled, the mixer can be used as a phase detector.
In addition, the mixer can be readily configured into an image rejection mixer or single sideband
modulator by adding an IF quadrature coupler.

All data presented is collected from a sample lot. Actual data may vary unit to unit.
All testing was performed under +25°C case temperature.
The I/Q mixer can be configured as an image rejection mixer or used as an I/Q up-converter,single sideband modulator and phase detector.
SAGE Millimeter, Inc. reserves the right to change the information presented without notice.

Caution:•••••Exceeding absolute maximum ratings will damage the device.
The mixer is a static sensitive device. Always follow ESD rules when working with the device.
The IF ports are DC coupled. Use DC blocks if necessary. Do not apply an external bias voltage
to the IF port.
Proper torque, 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm), should be applied. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
Any foreign objects in the waveguide will cause performance degradation and possible device
damage.
