SFT-71386315-122FSF-N1-M

Rev 1.0

Description:
Model SFT-71386315-122FSF-N1-M is an E Band subharmonically
pumped quadrature mixer that covers the frequency range of 71 to 86
GHz. The typical conversion loss of the quadrature mixer is 20 dB withan LO driving power of +16 dBm. With a low LO frequency range of 29
to 43 GHz, this mixer is well suited for low cost E band systemsolutions. The typical LO to RF port isolation is 30 dB. Since the IF portof the quadrature mixer is DC coupled, the mixer can be used as aphase 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, 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 (0.92 ± 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.
