SFB-10-N1

Rev 1.6

W-Band Balanced Mixer
Description:
Model SFB-10-N1 is a W-Band balanced mixer that utilizes
high performance GaAs Schottky beam-lead diodes and abalanced circuit configuration to offer superior RFperformance. The mixer supports the full waveguide band
operation for both LO and RF frequencies from 75 to 110 GHz
with an extremely broad IF output from DC to 35 GHz. The
mixer offers a conversion loss of 9 dB typical and a high RF toLO port isolation of 30 dB. While the typical LO to IF isolationof the mixer is 10 dB, it can be improved to 40 dB by adding
Eravant’s SCF-55375330-KFKM-L1 coaxial low pass filter.

W-Band Balanced Mixer
Note:• 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.
• 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.
• Eravant 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 (0.90 ± 0.02 Nm), should be applied. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
