SFB-50375315-1519KF-N1Rev 1.4

V Band Balanced Mixer with U Band LO Port, DC to 35 GHz IF
Description:
Model SFB-50375315-1519KF-N1 is a V-band balanced mixer with Uband LO port that utilizes high performance GaAs Schottky beam-leaddiodes and a balanced circuit configuration to offer superior RF
performance. With an RF frequency of 50 to 75 GHz and an LO
frequency of 40 to 60 GHz, the mixer supports the full waveguideband operation for both ports. The mixer also offers an extremely
broad IF bandwidth from DC to 35 GHz, a conversion loss of 15 dB
typical and a high RF to LO port isolation of 30 dB, respectively. The RF
port is the mixer is a WR-15 waveguide with UG-385/U anti-cocking flange and LO port is WR-19
waveguide with UG-383/U-M anti-cocking flange to accommodate low LO frequency operation.

Note:• 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.
• 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 (0.92 ± 0.05 Nm), should be applied. Eravant torquewrench, model SCH-08008-S1, is highly recommended.
