LIU Lei, ZHANG Gao-fei, YOU Zheng. Research on effect of environmental temperature on RF-MEMS switch pull-in voltage[J]. 2013, 32(5): 6-8. DOI: 10.13873/j.1000-97872013.05.032.
RF-MEMS switch has advantages on RF characteristic
power consumption and volume.Pull-in voltage is the important technical specification of MEMS switch.Effect of environmental temperature on pull-in voltage is studies.Impact module of environmental temperature on pull-in voltage is built up and theoretical formula is obtained.The change curve of pull-in voltage on environmental temperature is obtained through experiments.Experimental results indicate that in the range of-10
4
0 ℃
pull-in voltage descends with the decline of environmental temperature.Maximum voltage change(8.8V) is 15 % of pull-in voltage(58.6V) at-10 ℃
environmental temperature has important impact on pull-in voltage.
