SFQ-33350312-2222SF-N1-M

AdvancedDescription:
Model SFQ-33350312-2222SF-N1-M is a broadband
quadrature mixer that covers the frequency range of33 to 50 GHz. The typical conversion loss of thequadrature mixer is 12 dB with an LO driving power of+17 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 animage rejection mixer or single sideband modulator byadding an IF quadrature coupler. The mechanicalconfiguration offers an inline structure with WR-22 Uni-Guide™ waveguides. Other port configurations,such as 2.4 mm connectors, are also available under different model number, SFQ-30350311-2222SFN1-M.

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 mixer employs SAGE Millimeter’s trademarked and patent pending technology, UniGuideTM, as its waveguide interfaces. The orientation of the input and the output waveguides
can be specified through corresponding model numbers. For example, the model number for ahorizontal output waveguide configuration would be SFQ-33350312-22H22HSF-N1-M instead ofthe default SFQ-33350312-2222SF-N1-M which indicates vertical orientation output.
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 (0.92 ± 0.05 Nm), should be applied. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
