SFH-12SFSF-A3

Rev. 1.1

Description:
Model SFH-12SFSF-A3 is an E-Band balanced harmonic
mixer that is specially designed for using with Keysight’sspectrum analyzer series. The mixer employs highperformance, GaAs Schottky flip chip diodes, a highperformance built-in diplexer and a balanced configuration
to produce superior RF performance. The harmonic mixer isan even harmonic mixer, which works with LO frequency inthe range of 3.0 to 6.1 GHz. With an IF range of DC to 1.3
GHz, the harmonic mixer gives a calibrated conversion losstable at the 16th of LO harmonics at +16 dBm input power
level to translate RF frequency range of 60 to 90 GHz to IF frequency range of DC to 1.3 GHz. At 16th harmonicof LO, the harmonic mixer has a typical conversion loss of 45 dB.

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 -10dBm or below.
The Harmonic mixer work in any even harmonics of LO to yield the IF frequency in the range of
DC to 1.3 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.
