Liquid Metal-Based Tunable Linear Phase Shifters With Low Insertion Loss, High Phase Resolution, and Low Dispersion. IEEE Transactions on Microwave Theory and Techniques , 2023; 1 DOI: 10.1109 ...

The new phase shifter does not need cleanroom facilities for fabrication, so is inexpensive to manufacture. The liquid-metal enabled phase shifting elements have a ‘passive’ nature, unlike the ...

The HMC934LP5E is a GaAs MMIC phase shifter which is controlled via an analog control voltage from 0 to +13V, and provides a continuously variable relative phase shift of up to 400 degrees from 1 to 2 ...

The research team looked to address these long-standing issues by designing a new type of phase shifter that controls the phase shift via a liquid-metal material that runs in microfluidic channels.
