SFB-55375307-1519SF-E2

V-Band Externally Biased Balanced Mixer
SFB-55375307-1519SF-E2 is a V-Band, externally biased balancedmixer. The mixer supports a wide waveguide band operation with an RF
frequency of 55 to 75 GHz, a LO frequency of 40 to 60 GHz, and an IF
output from DC to 25 GHz. The mixer offers a typical conversion loss of8 dB. The externally biased mixer is used when high LO power is notavailable. Externally biased mixer works with low local oscillator (LO)power of 0 to +5 dBm when external bias of +5 VDC is applied. As a
trade-off, LO to RF isolation is lower compared to non-biased mixers.

NOTE:

The test data provided is collected from a sample lot. Actual data may vary slightly from unit to unit. All testing is performed
under +25 °C room 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.
To protect mixer from accidental static discharge, overbias and/or reverse bias, it is highly recommended to use voltageregulator (M/N: SOR-05-SM-R1) with this mixer.
When sufficient LO power is available, always use non-biased mixers to get optimum conversion loss and LO to RFisolation. Externally biased mixers should be used only if 13 dBm LO power is not available.
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 should be at least 5 dB lower than input P-1dB.
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 (+0.7VDC), which could upset the connecting device performance or even damage the device. Use a DC block whenconnecting 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 may damage or destroy the unit.
For 1.35 mm, 1.85 mm, 2.4 mm, 2.92 mm, and SMA connectors proper torque, 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm),should be applied. Eravant torque wrench model SCH-08008-S1 is highly recommended.
