SFM-77382312-1212SF-N1

Rev 1.0

Description:
Model SFM-77382312-1212SF-N1 is a E Band single side band
modulator that covers the frequency range of 77 to 82 GHz.
The typical conversion loss of the modulator is 25 dB with thequadrature IF driving signals of 6 Vp-p/3 mA for both I and Q
ports. The typical input/output isolation and image rejection is20 dB, respectively. In addition, the modulator can be readily
used as an I/Q mixer or image rejection mixer by using one of
the RF as LO port and/or adding the IF hybrid coupler.

E Band Single Side Band Modulator, 77 to 82 GHzNote: 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.
