A frequency mixing system including microwave coupling and intermediate frequency (IF) measurement arrangements is designed. In lieu of liquid nitrogen, a pulse tube cryocooler is used to cool the whole system. With YBa2Cu3O7/Yttrium stabilized zirconia (YBCO/YSZ) bicry-stal Josephson junction as the mixing element, 36th harmonic frequency mixing at the 8 mm waveband is obtained.

Wu Pei-Heng

Mixers with HTS YBCO/MgO,YBCO/YSZ bicrystal Josephson junction are researched on.Harmonic mixing at sub-mm wave band has been studied on two different HTS mixing systems:one is mounted on pulse tube cryocooler,the other is G-M cryocooler.We measured and analyzed the characteristic of Conversion Efficiency and its relationships with coupling coefficient,LO power,bias current,harmonic number and so on.

Performance Improvements of a Microwave Oscillator Using High Temperature Superconducting Harmonic Mixer

Weiwei Xu, Y.F. Zhang, X.K. Jiang +3 more

Based on YBa2Cu3O7Josephson junction mounted on a pulse tube cryocooler, a compact superconducting harmonic mixer is used to phase-lock a microwave source at 3 mm waveband to a reference of high precision at much lower frequency, thus greatly improving the performances of the former. Currently the highest harmonic number at which phase locking can be realized is 60. The experimental system, main results, and the problem of how to increase the harmonic number are discussed in details.
