SFQ-30340310-2828SF-N1-M

Rev. 1.2

Description:
Model SFQ-30340310-2828SF-N1-M is a Ka Band quadrature mixer
that covers the frequency range of 30 to 40 GHz. The typicalconversion loss of the quadrature 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 beused 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.
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.
Eravant 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.
Any foreign objects in the waveguide will cause performance degradation and possible devicedamage.
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. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
