SFQ-20330311-KFKFSF-N1-M

Rev 1.0

Description:
Model SFQ-20330311-KFKFSF-N1-M is a K Band quadrature
mixer that covers the frequency range of 20 to 30 GHz. The
typical conversion loss of the quadrature mixer is 11 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, themixer can be readily configured into an image rejection mixer orsingle 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.

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.
