SFH-19SFSF-A3

Advanced

Description:
Model SFH-19SFSF-A3 is a U-Band balanced
harmonic mixer that is specially designed for use with
Keysight’s spectrum analyzer series. The mixer
employs high performance, GaAs Schottky diodes
and a balanced configuration to produce superior RFperformance. With an IF range of DC to 1.3 GHz, theharmonic mixer uses the harmonic number 10 of a
3.0 to 6.1 GHz LO at +16 dBm to translate 40 to 60
GHz. The harmonic mixer has a conversion loss of 35
dB. The mixer can be used as other even harmonicnumbers, such as 6, 8 and 12, etc. with various
conversion loss performance. In general, the lower
the harmonics, the lower the conversion loss.

AdvancedNote:•••••All data presented is collected from a sample lot. Actual data may vary unit to unit.
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.
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.
