SFB-11340312-KFKFSF-N1-M

Rev 1.2

Balanced Mixer, 11 to 40 GHz
Description:
Model SFB-11340312-KFKFSF-N1-M is a balanced mixer thatutilizes a high performance pHEMT-based MMIC chip and abalanced circuit configuration to offer superior RFperformance. The mixer supports the wide waveguide band
operation from 11 to 40 GHz for both LO and RF ports. The
mixer also supports a broad IF output from DC to 10 GHz. The
mixer offers a typical conversion loss of 9 dB when the LO
port is pumped at +15 dBm. The mixer is ideal for highlinearity digital communication links.

All data presented is collected from a sample lot. Actual data may vary unit to unit.
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 mixer is a small signal device. The typical RF input level is 0 dBm or lower.
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.
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.
