SFQ-40350313-1919SF-N1

Rev 1.0

Description:
Model SFQ-40350313-1919SF-N1 is a U Band quadrature mixer thatcovers the frequency range of 40 to 50 GHz. The typical conversion loss ofthe quadrature mixer is 13 dB with an LO driving power of +17 dBm. The
typical LO to RF port isolation is 25 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.

Note: 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.
 Any foreign objects in the waveguide will cause performance degradation and possible device
damage.
