SFQ-70390315-1212SF-E1-M

Rev. 1.0

Description:
Model SFQ-70390315-1212SF-E1-M is an E Band quadrature
mixer that covers the frequency range of 70 to 90 GHz. The
typical conversion loss of the quadrature mixer is 15 dB withan LO driving power of +10 dBm. The typical LO to RF port
isolation is 40 dB. Since the IF port of the quadrature mixer isDC 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.

Note:• All data presented is collected from a sample lot. Actual data may vary unit to unit, slightly.
• 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 devicedamage.
