SFB-15-N1

Rev 1.4

V-Band Balanced Mixer
Description:
Model SFB-15-N1 is a V Band balanced mixer that utilizes highperformance GaAs Schottky beam-lead diodes and a balanced
circuit configuration to offer superior RF performance. The
mixer supports the full waveguide band operation for both LO
and RF frequencies from 50 to 75 GHz with an extremely
broad IF output from DC to 25 GHz. The mixer offers aconversion loss of 9 dB typical and a high RF to LO port
isolation of 30 dB.

Note:••••All data presented is collected from a sample lot. Actual data may vary unit to unit.
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.
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 externally biased mixer is DC coupled. Due to the external bias, it has a small
DC offset voltage (+0.7 VDC), which could upset the connecting device performance or evendamage the device. 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. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
