SFQ-75384315-1212SF-E1-M

Rev. 1.0

Description:
Model SFQ-75384315-1212SF-E1-M is a E Band quadrature mixer
that covers the frequency range of 75 to 84 GHz. The mixer requires
an external DC bias of +4.5 VDC and an LO power of +8 dBm, without
the requirement of additional port filtering, offering a cost effective
option for LO power requirement. A DC coupled IF port allows themixer to be used as a phase detector. In addition, the mixer canreadily be configured into an image rejection mixer or single sideband modulator by adding an IF quadrature. The typical LO to RF port isolation of the mixer is 30 dB,
which is high enough for most applications.

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 degrade performance and/or damage the device.
