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 RF performance. With an IF range of DC to 1.3 GHz, the harmonic 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 harmonic numbers, such as 6, 8 and 12, etc. with various conversion loss performance. In general, the lower the harmonics, the lower the conversion loss.
