SFH-08SFSF-A3-2

Rev. 1.0

Description:
Model SFH-08SFSF-A3-2 is a F-Band balanced harmonic mixer
that is specially designed for use with separate LO and IF ports.
The mixer employs high performance, GaAs Schottky diodes anda balanced configuration to produce a superior RF performance.
With an IF range of DC to 1.6 GHz, the harmonic mixer uses theharmonic number 12 of a 5.0 to 12.0 GHz LO at +16 dBm totranslate 90.0 to 140.0 GHz. The harmonic mixer has a typicalconversion loss of 42 dB. The mixer can be used as other evenharmonic numbers, such as 10, 14, and 16 etc. with variousconversion loss performance. In general, the lower theharmonics, the lower the conversion loss. Other models, such as
SFH-08SFSF-A3 are offered for the spectrum models other than
Keysight’s 856X series are also offered in the our website here.

Note:
••
•

The harmonic mixer is for small signal detection. The recommended the RF power range is -10
dBm or below.
The Harmonic mixer work in any even harmonics of LO to yield the IF frequency in the range ofDC to 1.6 GHz with different conversion loss.
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.
