SFB-19-N1

Rev 1.4

Description:
Model SFB-19-N1 is a U-Band balanced mixer that utilizes highperformance GaAs Schottky beam-lead diodes and a balanced
circuit configuration to offer superior RF performance. Themixer supports the full waveguide band operation for both LO
and RF frequencies from 40 to 60 GHz with an extremely broad
IF output from DC to 20 GHz. The mixer offers a conversion
loss of 8 dB typical and a high RF to LO port isolation of 30 dB.

All data presented is collected from a sample lot. Actual data may vary unit to unit slightly.
All testing was performed under +25 oC case temperature.
A DC block at IF port may be required when connecting to a device, such as an IF low noise
amplifier or a base band mixer which input port is DC coupled.
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.
Never apply an external bias voltage to the IF port because the mixer will be damaged.
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.
