SFT-70376315-12KFSF-E1-M

Rev. 1.0

Description:
Model SFT-70376315-12KFSF-E1-M is an E Band subharmonically
pumped quadrature mixer that utilizes high performance GaAs MMIC
chips to offer superior RF performance. The mixer operates from 70 to 76
GHz with 15 dB nominal conversion loss. The required LO frequency andpower are 35 to 38 GHz and +16 dBm, respectively. The amplitudeunbalance is within ±1 dB and the phase unbalance is ±20 degrees
typically. The IF frequency ranges from DC to 5 GHz with good RF to LO
port isolation.

Note:
••
•

All data presented is collected from a sample lot, actual data may vary unit to unit, slightly.
All testing was performed under +25oC case temperature.
SAGE Millimeter, Inc. reserves the right to change the information presented without notice.

Caution:•••••Exceeding absolute maximum ratings shown will damage the device.
The device is static sensitive. Always follow ESD rules when working with the device.
The IF port of the mixer is DC coupled. Use a DC block when connecting to other devices. Do not
apply an external bias voltage to the LO and IF ports.
Any foreign objects in the waveguide will cause performance degradation and can possibly
damage the device.
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.
