Coupling microstrip line bandpass filter applied to hybrid frequency synthesizers
Dianzi Jishu Yingyong, 2018 This paper designs a parallel coupled microstrip bandpass filter at the ends of the hybrid frequency synthesizer of PLL+DDS mixing in the outside of the feedback loop systems. This filter is used to suppress the frequency synthesizer′s spurs and harmonic

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 650-665, August 2026.ABSTRACT Purpose Ultrahigh‐field MRI requires careful management of the specific absorption rate (SAR), which is subject and subject‐position dependent. Within‐scan subject motion may exacerbate local SAR exposure, necessitating large safety margins to prevent SAR underestimation, which hampers imaging performance.
