提出了一种采用无毒液态金属Galinstan实现的电致动直接接触式射频分流开关。Galinstan由5-VDC信号驱动，可诱导电毛细管作用。局部表面能量威尔斯井促进Galinstan的亚稳态锁定，从而实现ON/OFF锁定，而不需要连续施加的偏置电压。该开关的工作频率范围为DC至11.2 GHz，隔离度大于10 dB，插入损耗小于3 dB（DC至6.7 GHz）。
An electrically actuated direct-contact RF shunt switch implemented with the nontoxic liquid metal Galinstan is presented. The Galinstan is actuated with a 5-VDC signal that induces electrocapillary action. Local surface-energy wells facilitate metastable locking of the Galinstan, thus achieving ON/OFF locking without requiring a continuous applied bias voltage. The switch operates from DC to 11.2 GHz with greater than 10 dB isolation and has less than 3 dB insertion loss from DC to 6.7 GHz.
