SFH-22SFSF-A3-2

Rev 1.0

Description:
Model SFH-22SFSF-A3-2 is a Q-Band balanced harmonic
mixer that is specially designed for use with spectrum
analyzer series with separate LO and IF ports. The mixer
employs high performance, GaAs Schottky diodes and abalanced configuration to produce a superior RFperformance. With an IF range of DC to 1.6 GHz, the harmonic
mixer uses the harmonic number 6 of a 5.0 to 12.0 GHz LO at+16 dBm to translate 33.0 to 50.0 GHz. The harmonic mixer
has a typical conversion loss of 25 dB. The mixer can be used
as other even harmonic numbers, such as 4, 8, and 10, etc.
with various conversion loss performance. In general, thelower the harmonics, the lower the conversion loss.

Note:
•••
•
•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.
