SFH-08SFSF-A3

Rev. 1.0

Description:
Model SFH-08SFSF-A3 is a F-Band balanced harmonic mixer
that is specially designed for use with Keysight’s 856X series
spectrum analyzer series. The mixer employs high performance,
GaAs Schottky flip chip diodes and a balanced configuration toproduce superior RF performance. With an IF range of DC to 1.3
GHz, the harmonic mixer uses the harmonic number 24 of a 3.0
to 6.1 GHz LO at +16 dBm to translate 90 to 140 GHz. Theharmonic mixer has a typical conversion loss of 48 dB. The mixer
can be used as other even harmonic numbers, such as 22, 26,28, etc. with various conversion loss performance. In general, thelower the harmonics, the lower the conversion loss. Othermodels, such as SFH-08SFSF-A3-2 are offered for the spectrum
models other than Keysight’s 856X series are also offered in the our website here.

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.
• SAGE Millimeter, Inc. reserves the right to change the information presented without notice.
Caution:• Exceeding absolute maximum ratings of the mixer will damage the device.
• Any foreign objects in the waveguide will degrade performance and/or damage the device.
• The mixer is a static sensitive device. Always follow ESD rules when working with the mixer.
• Proper torque, 8.0 ± 0.15 inch-pounds (0.92 ± 0.05 Nm), should be applied. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
